Nitrogen Cycle Spike

Recommended Posts

Neos in Woodstock

Although I read that most shrimp keepers/breeders do so in a shrimp only tank, I wanted to try keeping them with fancy guppies. Unfortunately, as a newbie I think I overfed and now have had a spike in the nitrogen cycle. A few days ago, I cut back on the feeding to the detriment of the newborn guppy fry as they became dinner for the adults, and performed 50% water changes while also adding Seachem Stability. Does anyone have any other suggestions that will lower the ammonia and nitrites/nitrates faster? All seems good at the moment but I have to keep adding Stability to bind the ammonia etc while my sponge filters pick up the difference.

Also, how often should I be rinsing out the sponges in aquarium water? Once a month? Less or more often? They never look very dirty.

I would not clean my sponge filters unless they are visibly clogged with dirt. There is no specific timeframe. Just squeeze it clean only when you see a lot of dirt clogging the sponge.

Have more than one sponge filter going, in a separate tank. When this happens, you transfer that into the tank.

Or wash the filter from another tank straight into this tank. Yes, it will be dirty, but you seed the tank with millions of beneficial bacteria. The dirt can be removed later once the tank is back under control.

ammonia spike don't just happen, unless there was so much food uneaten that caused the issue.

Care to share your tank parameters with us to see if we can spot in issue? Temps, pH, TDS, KH are primary parameters that will determine the health of the bacteria. If you have ammonia test kits, take a reading as well, since that is what is being suspected here.

Keeping shrimps esp the more expensive finicky ones in a grow out tank for fry is going to be very complicated. Dry grow out would need multiple feedings, water changes where as shrimps would need more stable parameters.

The guppies will  also enjoy eating shrimplets!

Thanks for all of the info guys. All three of my tanks have neocaridina.

Yes, I know that fry will be lost without multiple feedings daily because the adults will be hungry. And shrimplets will be lost too whenever the parameters are good enough for them to be born. I have excessive plantings (dwarf sagittaria and water wisteria) and water column plants (hornwart, frogbit, and java moss) as well as a lot of rocky (dragon stone) and Malaysian Driftwood crevices for the shrimp and mystery snails to hide.

The parameters yesterday of all three tanks are: TDS-220-225; Temp-71.8-76.3; PH-7.5-7.6, GH-9, and KH-4. Ammonia has been spiking up to 1.0, Nitrite to .25, and in one tank the Nitrates were elevated to 3. 

If I understand correctly, even "bound ammonia and nitrites" (using Seachem Stability) will show up in the API Master Test Kit where as they don't with test strips.

In all three tanks I have multiple (2) sponge filters and in the two larger ones I also have HOB filters running very slowly that came with the aquariums.

Are you saying all 3 tanks are showing readings of ammonia and nitrite?

No. Just two of them.

Have you washed your filter media/sponge from the good tank into the ones having ammonia issues?

If you do that, you will add beneficial bacteria back in.

Your tank parameters look fine for both shrimp and the bacteria, so any bacteria added to the tank now will survive.

      Failed moults are usually associated to Calcium content in the water. That is, your GH reading. Too much GH and the shells (and eggs) become too hard and moulting becomes difficult. The shrimp looses too much energy trying to moult. Too little and their shells don't develop properly causing deformities (maybe GH under 2). This is a long term affect, that is, if you see it, it's already too late and nothing you can do to help a shrimp that is having issues right now.

      I'm not sure there woud be much you could do in that situation, hopefully someone else may have some ideas! The stress of the moving added to the waater change and  the mout is likey to be too much all in one go! Even without the obvious moult I woudn't personally expect all the shrimp to survive and usually a few disappear/die in the first 2 weeks! If you got them from a shop they have already beeen through a lot going from the breeders tank, transit, into shop tank (different water probaly), transit, into your tank (again new water) at the very least, there could even be another wholesaler to add to that? I always used to buy direct from hobbyist (ebay) which meant just going from their tank, transit (post), to my tank, but even then I usually lost a few in the first 2 weeks. I did once see a youtube video where someoone helped a shrimp moult by using tweezers but that is very fiddly, you would need to fish the shrimp out and put it into a smaller container, and it likely still wouldn't work, even if the shell were removed it may die in the next few days from stress......... If you try anything please let us know how it goes! Hopefully some others will have some ideas? On the ratio issue, most people would prefer more females to males as you only need the one male to breed with the females and you will get more baby shrimp the more females you have! There is probably another issue if they aren't breeding and you have both sexes? Simon

      Phew, glad it has ended well for you and the rasboras.

      I was quietly hoping you would write a guide. Well done, with the guide. The shopping list makes it very easy looking for parts.
