copper test kit

Recommended Posts

xrayguy

hi guys and gals

I was discussing my lack of sucess with rcs shrimp with my lfs guy, and he asked me to bring in a sample of my tank water.  He tested it for copper.  He said my tank water was high in copper.  

I do have copper pipes, and he believes that's the cause.  I have a 72g med/high light planted tank with co2.  My po4 is higher than I'd like(3.), and I kinda think that might be my cause, but I don't want to discount the copper thing either.  

 

So I'm wondering if the API test is the best 1 to get or is there a better version to get.  I'm about to set up a shrimp only tank ( fluval flex9) and want them to live and breed happily.  Gonna buy distilled water from the store until I can prove it's not my water.

thanx

Hanna low range copper test kit colorimeter, measures in parts per billion.

In the mean time, you can use Prime to help bind the copper, and there are also copper-absorbing chemicals.

I would also be worried about using CO2 and tap water rarely works with caridina?

Is the plan to move the shrimp to their own tank? If so you probably should get RO water and remineralise with shrimp specific GH+ for the best results. For RO water you can use a Zerowater filter jug if you don't want a full RO system, which is very cheap in USA and available from Walmart, internet etc. It is slow to filter so may not be pracrical for a very large tank but if the shrimp are being moved to a smaller/new tank that should sort you out. I get about 100 litres per filter! It will remove any copper.

Yes, I'm starting a shrimp only tank.  No co2, no ferts.  

I only want to have bloody mary shrimp in flex 9.

thanx

This bloody RCS and CRS nonsense again, sorry, my bad, I thought you had crystal shrimp but now see you have red cherry!

The same applies though except you need GH/KH+ for red cherry/bloody mary shrimp. You can still use the zerowater to convert your tap water to RO water though and then mineralise it in the new tank! Those flex aquariums are very nice, it may need some tweeking though to ensure it is shrimplet safe, and stop them getting into the back 'workings' section! 

You can also use seachem prime with tap water, as stated by Beanbag and neocaridina are usually fine with such treated tapwater so it would be worth trying with that first, as it will be easier and cheaper than going RO + minerals route?

      Thank you again for all of the excellent advice!! Yes!! I didn't actually introduce the trumpet snails on purpose. Either the plants from my local independent pet store had hitchhikers or the plants from Petco had some. I rinsed them thoroughly didn't quarantine them so it's my fault. I will catch all but 1 and put them in my turtle tank. Never a short supply of algae in there even with 4 snails and a bn pleco. Neon tetras are super readily available here.  I introduced a single snail and it hasn't reproduced yet. It's black and I can't remember the name. And with a bristlenose pleco there is still a lot of biofilm and small food particles to clean. I really did a number overfeeding because there's food all over even after sectioning the substrate + 2 WCs. I'm feeding a teeny tiny amount every few days on top of the biofilm. They take hours to eat it all.  It's hard to tell how much to feed, I wish there was a care guide just on that part. I have omnivore shrimp pellets which are discs, I feel 1/4 of those and a tiny piece of a pleco pellet (disc) and a few tiny granules of herbivore invert pellets. That's every 3 days but I could probably go 4 or 5 with all the biofilm. I have a heater but never use it except for the biofilm. It's a favorite for grazing and it's now spotless. Had a gross crust a few days ago.

      I have heard and seen L Bretz videos but I didn't think he was USA based so didn't mention him. His website doesn't say where he is based from my brief look but if he is USA, he is well known in the hobby! The caridina are definitely worth the extra work IF you can get it to work??? They may need some form of cooler in the summer where you live unless you run air-con a lot. My cherry shrimp are ok to about 85 (tanks haven't gone above that ever here) or possibly higher, but when I had caridina 79 was when it started to get tricky? Simon

      Probably (as JayC recommended) a neon tetra or 2 may be worth a try, tetras spend most of their time midway in the tanks depth of water. My oldest tank has 5 ember tetras, 5 neon tetras and ??? red cherry shrimps and I have never seen the fish go for the shrimp in the 5 years+ it has been running, though there is a lot of subwassertang (?) to hide in and most shrimps are now boring brown/clear so they are hard to see and maybe don't look tasty to the fish. Neon tetras are also cheap and readily available, here anyway? The malasian trumpet snails will help clear the overfeed - by the way we have all made that overfeed mistake at the start - but they can be a problem in their own right as they breed so quickly? I have occasionally spotted detritis worms but never had an infestation and probably every tank has them anyway. An infestation of those would indicate over feeding. Any fish will likely eat them. Don't worry about a few of those, they are harmless enough and I think every tank has them! It  sounds though, that you have a lot competing for food, shrimps, worms, snails, copepods all in a small  tank....... Simon

      Thank you Crabby & Simon!! I'm not able to like posts for the rest of the day, but I definitely will +1 both of your replies when I can. I greatly appreciate the recommendations. I won't be making any purchases to ship anything live until about a month from now. We're still getting into the 40s F at night here in the mountains. I've been reading up on Caridina tanks and they're much higher maintenance, but I think definitely worth it. Buffering substrate, much more specific parameters, additional nutrients & specialized foods. I'm starting to build up an inventory now for adding more tanks and when I'm brave enough to get into caridina.  I'm hoping to purchase from multiple home breeders to get enough genetic diversity so I'm hoping to get a multitude of recommendations. 🤞🤞🤞🤞 Edit: Another breeder I saw recommended from a post back in May is L.R.Bretz Aquatics.

      Thank you Simon!! I have read all of the posts from the past year or so (down the rabbit hole I go), so I did see your comments about the seed shrimp infestation. Nasty little cocroaches!! Everyone seems to be in agreement on the killies, dwarf rasboras & neon tetras. I think I will have to suck it up and grow some ground cover so I can add a single nanofish to keep the pest population down but still keep my shrimplets safe. I found 2 detritus worms floating yesterday, although I can't see any in the parts of the tank which are visible. Which I know means there are many more I can't see. There is a back corner I can't really get my eyes on, I'm sure they're there. I just did 2 WCs this past week because overfeeding caused food particles to be everywhere, and suctioned the substrate in the front of my tank. Thankfully my berried female did not molt. In the back end of the tank are the hiding spots and an especially good hiding spot that is planted in the corner. I think I have the feeding down now, every few days and very tiny amounts. They actually ate nearly all of the food this last feeding. I'm probably going to be dealing with the effects of my overfeeding thus far for weeks until my cleaners can get to it all. My trumpet snails will literally dive into the substrate to get to the food particles. Amazing little buggers.
