Tank cycle question


Mitch91

Recommended Posts

So I went out and brought two new 1.5ft tanks as you may already know can't remember if I posted lol anyway these will be dedicated to shrimp only and plants. My question is day 3 of cycling is this normal readings. 

Tank 1 and 2 both read the same both have Ada Amazonia soil. 

Ph - 7.6 but on high range it's 7.4

ammonia - 0ppm

nitrite - 0.50ppm 

nitrate - 5.0ppm

0 ammonia in a 3 day old tank with ADA is not normal. You should be swimming in it.

the soil was 3 months old when i got it if that makes a difference?

why would i have 0 ammonia but still show nitrites ? and how long until my ph buffers down?

yes, that does make a difference.

This would only make sense, if you are using mature filter media, ie, filter media that already has beneficial bacteria on it.

Are you using old filter media??

Depends on how quickly your tank cycles. No one can give you an accurate timeframe.

You can quicken the cycling by providing the bacteria an optimal environment. Heat, oxygen and food source.

Heat = temperatures of 27-28 deg C - have you got a heater in there?

Oxygen = water movement by way of your filter.

Food source = ammonia & nitrites.

something is not right there the ph should be down around 6. I think then soil might be older than 3 months.

perhaps you should let everything sit for 24hrs and take some more readings!

ive added plants from an established tank, a bit of gravel thats in a mesh bag from the established tank. heater yes its active on 27 degrees, i also added some water from my already running tank into this tank.

yes well 3 days id think it would be down too but idk im confused first time using these sorts of soils, i really hope it does drop down into the 6s

That would explain it then.

There is some BB (Beneficial Bacteria) on the plants and old gravel to process the ammonia but not enough BB to completely process all the Nitrites from your 3 month old substrate. And since the substrate has already been used and cycled in a previous tank, it does not have the usual ammonia release like brand new Amazonia.

oh okay how long do you reckon until its usable ? so the ph will buffer down once its cycled ?

Keep testing Ammonia and Nitrites regularly. When they reach zero, it's ready.

Yes. The process of nitrification reduces pH.

Should I do water changes ?

Not necessary yet while ph is still in the 7s.

When pH drops below 6, BB will start slowing down, and can stop functioning at pH lower than 5. That is the  time to change water, at pH 6, with dechlroniated tap water to bring the pH back up.

Alrighty then thanks so much for your help and sorry for so many questions only new to all this with aqua soils.

No problem. Now that you are an expert on cycling, you could help the next person :)

 

Having a look at your tests again, the ammonia is more 0.25ppm rather than 0ppm.

Yeah those test where done this morning, I have to agree with the 0.25ppm.

Well, good luck.

      Update to say that after a few gravel vacs, front wall scrub, moss / floating plant trim, that the condition seems to have improved.  My current theory is that it is due to waste / debris management, where "stuff" like that brown mulm accumulates in the substrate and behind the HMF filters.  Maybe some tanks can somehow deal with it, but mine can't.  Also another experienced shrimper suggested that maybe those "shell bugs" don't just live on the shrimps but also in this debris.  Maybe this is the reason some tanks fail due to "old tank syndrome" where all they need is a good gravel vac? Also, I am guessing that plant trim helps too because now more of the nutrients and light go into growing algae instead of more plants? Well anyway for this tank I will try weekly water change and monthly gravel vac / plant trim.  For my next tank, I'm thinking of something like an under-gravel system where this mulm can fall down and I vac it out.

      Good to have an update and good to hear you are getting shrimplets, so hopefully your colony will continue and you may not get to the point where you have to cull some to stop over population. These type of shrimp only live 12 - 18 months so the adult deaths may be natural? If you have the time I would do weekly 25% water changes, adding the new water via a drip system and do some vacuuming clean of the substrate each week, even if only a different bit each week! See if that helps in a few months and if it does then stick with that regime? It should help reduce any build-ups that may be occuring!

      Hello again, much belated update: The tank still has "cycles" of 1-2 month "good streaks" where everybody seems to be doing well, and then a bad streak where the short antenna problem shows up again, and a shrimp dies once every few days.  I am not sure what causes things to go bad, but usually over the course of a few days I will start to see more shrimp quietly standing on the HMF filter, and so I know something is wrong.  Since I am not "doing anything" besides the regular 1-2 week water changes, I just assume that something bad is building up.  Here's a list of things that I've tried that are supposed to be "can't hurt" but didn't prevent the problem either: Dose every other day with Shrimp Fit (very small dose, and the shrimp seem to like it) Sotching Oxydator Seachem Purigen to keep the nitrates lower Keeping the pH below 5.5 with peat Things that I don't do often, so could possibly "reset" the tank back to a good streak, are gravel vac and plant trim, so maybe time to try those again. One other problem I used to have was that sometimes a shrimp would suddenly stop eating with a full or partially full digestive tract that doesn't clear out, and then the shrimp will die within a few days.  I suspected it was one of the foods in my rotation - Shrimp Nature Infection, which contains a bunch of herbal plant things.  I've had this in my food rotation for a few years now and generally didn't seem to cause problems, but I removed it from the rotation anyway.  I don't have a lot of adult Golden Bees at this point so I can't really tell if it worked or not. Overall the tank is not too bad - during the good streaks occasionally a shrimp will get berried and hatch babies with a 33-50% survival rate.  So while there are fewer adults now, there are also a bunch of babies roaming around.  I guess this tank will stagger on, but I really do need to take the time to start up a new tank.  (or figure out the problem)

      If that is the offspring, then the parents are unlikely to be PRL. I tend to agree with you. There are very few PRLs in Australia. And any that claim to be needs to show proof. PRL genes have to start as PRL. CRS that breed true after x generations doesn't turn it into a PRL. Neither can a Taiwan bee shrimp turn into a PRL despite how ever many generations. I've never seen a PRL with that sort of red colour. I have on Red Wines and Red Shadows - Taiwan bee shrimps. So somewhere down the line one of your shrimp might have been mixed with Taiwan bees and is no longer PRL. It just tanks one shrimp to mess up the genes of a whole colony.

      Sorry, missed this one somehow! The PRL look fantastic and the odd ones look part PRL and part Red wine/Red shadow in the colour. They are still very beautiful but ideally should be seperated to help keep the PRL clean if you can do that.  Nice clear photos!
