Green algae

Recommended Posts

OzShrimp

Just wondering what people do to deal with their green algae? Scraped the front of my tank clean yesterday and one side.  I attempted to scrape it off the back but it was so freakin hard i ended up giving up lol

I am attributing it to running 2lights instead of 1 so cut back to 1 (unconfirmed).

Slowly need to start cleaning it up though as my tank will be packed up in 4 1/2 months.

 

Anyone know of any shrimp safe stuff to use other then bit of elbow grease!

I just use a safety blade and scrape - it comes off fairly easily. I run 3 lights 8 hours a day. It did help when I had a break with lights off after 4 hours but I don't bother anymore.

yeah i got the aquaone scraper but i dont think its sharp its just a blunt blade cause i have to really scrape it on the hard green on the back of my tank but other parts is like butter.

 

When you say safety blade what do you mean?

I bought this recently and it is freaking awesome!!! I could easily scraped both thin and thick layers of algae off the glass. Comes in either 46cm or 65cm.

I bought the 65cm one which works great for my 4x2x2. Full stainless steel and very well built. I even received 3 razor blades in the box with it.

Not sure if ebay link is allowed so if this is removed by any mod, please feel free to shoot me a PM.

Oops... just realised you're a mod. Haha. So yea, please remove the ebay link if not allowed and shoot me a PM. Haha. Sorry.

I bought some blades from Bunnings similar to a Stanley knife blade but they have an edge turned over so you can safely use them by hand. They were about $10 for 50 I think. They last quite a while as long as you dry them after each use

ebay links are fine thanks for that :) 

This is what i am currently using and is alright for fresh algae but anything not recent i find i am having to use the corner of the blade.

Might look at getting one of those scrapers you got @jc12 . How long have you been using them and would the blade be replaceable with say a different razor blade like @ineke uses if it was cut to size ?

The algae in one of my tanks (sump) was probably 6-8 months old and I couldn't even see through the glass at some areas. Some of them are those hard stubborn green spot algae and I didn't need much effort removing them.

I forgot to ask you if you have an acrylic or glass tank. Do not use this on acrylic tanks. It will scratch.

I am not sure what type of blades ineke meant but the blades that came with the scraper are like these ones.

The blade is sandwiched between a metal plate and the handle, and held on by two thumb screws. I always unscrew and disassemble them and leave them out to dry completely before putting them away in case water trapped between the plates would cause the blade to rust.

Hope this makes sense else I could take some photos for you when I get home later.

oh sweet you answered my question, i was wondering what type of blades they came with.

 

thats a normal safety razor blade!!! what i got loads off, sweet, buying one of these

Cut back the amount of light is the trick and a couple of Bristlenose will help big time.

 

I also bought some plastic razor blades, safety type and they are BRILLIANT, safety as in one sided and they are red colour, work a treat

Yeah what Bob said! You can buy red nylon safety blades on ebay, won't cut you and even better won"t scratch your glass. If you use steel blades better make sure they're brand spankin new. They rust quick in a fish room and any little imperfection on the blade scratches glass. 

The "Flipper" cleaners are the best if you want a magnetic one. They're not cheap but worth the money if you like magnet cleaners and use them regularly. 

FWIW I made a decent scraper from a piece of clear acrylic, cut the blade on a bench grinder and cleaned it up with some wet dry sand paper. Works great and I got it the same day i needed it, no wait time. 

 Oz you could try reducing the light cycle rather than intensity, some shrimpers seem to like a couple of hours off in the middle of the day. Or you could try "AlgaeFix" (Aquarium Pharmaceuticals) - research it yourself. You'll find reports of everything from "100% shrimp safe" to "killed everything". Tom Barr says it kills about 30% of shrimp in some tanks and I trust him to have got the dose rate correct. 

Sometimes blackwater additives reduce algae growth - that would include IAL etc. The tannins are the inhibitor. Barley straw releases something that stops algae growth so you could try a liquid barley extract (try pond suppliers inc. Bunnings) or barley pellets/fermented straw. These options are shrimp safe but possibly less effective. If you have 4 months you should be right.

If it's green spot algae you are getting, dose a little bit of phosphates (either liquid ferts or K2PO4 powder) and it will halt the growth of it. It's generally a sign of low phosphates in a tank with plants.

The best way by far is Native Nerite snails, they are better than Bristlenose by a mile and don't eat plant, one draw back, some dig in the substrate, so far there has not been a issue for me and I use laterite under my substrate

Another possible draw back with nerites is that their egg capsules can look a bit ugly and can be difficult to remove (particularly from rocks and other rough surfaces, less so from glass). However I've found this is depends on the species of nerite kept and may vary between individuals. Neritina pulligera and the tiny limpets dont seem to lay eggs anywhere but my other ( unknown) species does.

I had green algae not to long ago ! 

It was pretty bad 

I went to my mums place and grabbed out 6 juvi (2/3cm) and threw them in !!!!! 

Less then a week later and there's not 1 spot of green algae anywhere :) 

let me know if you want Afew when you are in Sydney next oz

If you were going to try the barley pellets or straw then they must be placed where they have water flow running over them continually. This is what causes the out shell to break down and causes the chemicals to be released that assist with algae issues.

The extract is easier to use or API do an algea inhibitor that is safe and in liquid form. I have had a discussion with one of the head guys from the company that manufactures this and he has assured me that it will not kill shrimp or fish. I can get you the details if you want them. One of the guys I work with uses and swears by it.

As far as barley straw goes and bi-products from speaking to numerous customers and researching it myself you could ask 100 people and 50 would say it is the best thing since sliced bread and 50 will tell you it dosent work and is a waste of money.

I am still sitting on the fence about it but the other thing you could try and is 100% safe is Aquatek pond clarifier. It takes about 8-10 weeks to start working effectively and is added in powder form to the tank every two weeks.

The API one is "AlgaeFix" which I referred to above. Check Tom Barr's testing because it can, and does kill shrimp sometimes.

This green algae, what exactly is the algae? The ones that look like hair? Or clumps of green spots

I would recommend bristlenose catfish as others have already in this thread however I would place them in the sump to clean the algae off free of charge, also providing clean filtered water free of algae spores. I find the smaller ones are better at cleaning than the large ones which are only interested in breeding.

      Hey guys, just found an add for this website showcasing a cool-lookin native algae eating shrimp.
      https://algaeeatingshrimp.com.au/products/australian-algae-eating-shrimp
      Anyone heard of these before or own any? My interest was peaked by the claim that they eat hair-type algae, as I have some on my crypts and lace fern that I cannot remove. And for a price of $4 ea, and super easy parameters, they sound pretty doable! 
      Tell me more oh great SKFians! 😁
      (or feel free to point me towards an already existing page)

      Hello, just wanted to show another food source I grow for my shrimp and snails. 
      Algae.
      Just how it looks, a plastic tub filled that gets lots of direct sun, I usually fill it with old water from my planted tanks to help the process.
      Its a bit full ATM lol but there's a second tub underneath for extra strength.

      I just grab a small pinch and put it straight in my shrimp tanks, they all go nuts for it.
      Alternatively you could remove excess water then dehydrate it on baking paper to make a dry feed.

      An hour or 2 later:

      A Generally accepted method of spot dosing with H2O2 (Hydrogen Peroxide)
      We will work with a 30cm cube to make all calculations easier (30L of water) and be using 3% solution of H2O2
      Remember you are playing with a chemical that oxidizes when it comes in contact with organic matter, so always use as little as possible as overdoses can damage your invertebrates (shrimp) or nitrifying bacteria causing your tank to cycle again.
      MAXIMUM dosage in a 30L body of water is 15ml in a 48 hour period, this will increase total peroxide levels by 15 mg/l, generally this is deemed safe, but always best to work well and truly under this level.
      Things you will need:
      Half hour of time
      Hydrogen Peroxide (3% solution) - easily purchased from your local super market or pharmacy
      1x 10ml syringe, these are available relatively cheaply from your pharmacy
      Prepare your tools:
      Draw up 5ml of your H2O2
      If this is the first time you're doing this, before you start the actual dosing process add 2.5ml of tank water as this will give you slightly more ammo to play with without increasing your overall dose.
      Prepare your tank:
      Turn off all filters and pumps.
      This is so you don't have a current in the body of water (should only take 30seconds to settle). also if your dosing near your intake best to avoid getting H2O2 in the filters as it will go bananas on all the good bacteria you have in there.
      Plan your attack:
      Take a step back look at what your treating and figure out if you have more than one place to dose or if its just localized less time your filters are off the better.
      Not an Ideal situation to be fiddling around for an hour with your filtration off
      Attack:
      Dose sparingly directly above the site you wish to treat, within a second or two you will see it bubbling away. try to avoid sensitive mosses and such if in doubt patch test first.
      An example of what the effect is:
      Finish up:
      Wait a couple of minutes and turn everything back on.
      It is generally suggested to do a water change (one third) if you wish to re-dose within 48hrs, but as we are only playing with a third of the maximum dosage you can repeat this the next day if you feel it necessary, or if you have more algae than this dosage allows you to treat.....
      Good Luck and if in doubt ask questions on the forum, there is plenty of experienced shrimp keepers that are willing to help out!!!!

      Thank you for all the help. I believe the issue was a bacteria. Deaths have stopped so far. Shrimps are very active, they keep molting and there's still 1 berried female. I keep doing water changes until it cycles, and half the tank doesn't have the fuzzy white thing anymore. The other part does still.
    • Crystal Jade
      I haven't been able to find an ammonia test kit so maybe that was my problem but I woke up to no dead shrimp. Before I do a water change I want to make sure my water I have is correct with water parameters and GH and KH  especially. I did cycle my tank and it should be fully cycled by now.    Thank you all!
    • sdlTBfanUK
      Sorry to hear you lost some shrimps! How big is your tank and how long has it been running? Did you do the 'cycle'? When doing a water change you should drip the new water into the tank. That will illiminate the temperature difference problem and any difference in parameters between the two waters. When acclimating new shrimps you should drip acclimate them as long as you can, the longer you do that the better chance they have of survival. You will need to match the water temperature to that of the tank by floating the container with the shrimp in the tank once you have stopped dripping, before adding the shrimp to the tank! The parameters you have I would think are acceptable so I would stick with tap water if that is what you are using, for now. RO water is ideal but you will then need to buy GH/KH+ to add the minerals. As I say, I would hold off using RO/distilled water for now until we can pin point the problem. If your water has a green tint to it that may be an algae bloom? A white tint is usually a bacteria bloom and I have only seen that whilst a tank is 'cycling'. I think an algae bloom will mean there is less oxygen in the water as the algae absorbs it?????? Overfeedinng is very common. It will depend upon the size of the tank and how long it has been running etc. With only a few shrimp there may actually be no need to feed additional to the natural biofilm of the tank. As shrimps are feeding all day on biofilm it is usually better to see additional food as just a treat and feed very sparingly. Overfeeding with shrimps doesn't usually mean that the shrimps over eat, it usually means  too much uneaten food polutes the water and if you have green tinted water, algae bloom, that may be why? There usually comes a time, if you are lucky, that there are too many shrimps in the tank for the biofilm to sustain on its own, so as the population grows feeding may become more necessary. Shrimp don't usually hide unless they are new to the tank or there are fish etc (even then they will usually adapt to them) or as JayC says, their is something wrong with the water quality?  Simon
    • Crabby
      Sorry... this was meant to be partially sarcastic. I mean it's a bit sad but I don't really mind all too much. Yeah they're like that, with those big mouths. 
    • jayc
      Rather than using "time" as a guide we should use the water parameters as the reference of when the shrimp/fish has had enough acclimation.  Now that you have (or will have) a TDS pen, you just need to measure the TDS of your tank and the water the shrimp came in. Lets say your tank TDS = 150. And the water the shrimp came in = 200. So you start dripping water into the bag the shrimp came in. You keep dripping until TDS is close to 150 (TDS of your tank water). Say 155 TDS should be ok. This take as long as it needs to reach close to 150TDS. It could be 1 hour. It could take 12 hours. This is why I will hesitate telling someone that 1-2 hour drip acclimation is enough. It all depends on the start water parameters and how fast the drip is going. Anyway, good luck, and I hope you sort the issue out without too many more deaths.
