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.

      So I did some research on chimerism in shrimp today. It appears it is true chimerism and apparently some shrimp exhibiting are either sterile or unable to breed due to potentially mixed sex organs.   I believe I know a common origin point of chimeras, and also that I know who the dam(?) of that shrimp is and that she conferred the trait. For now mum is the word until I test my theories by inbreeding the pair and or outbreeding the chimera.

      So i would just follow your ratio ca:mg as per your diy mix for the sulawesi? besides using ro water to dissolve it, are there any other easier ways to make it dissolve in water? And when you mean cold, is like 20celcius okay? Sorry if im wrong, pounded down as in getting a mortar and pestle and pounding it down? Sorry if im asking too much

      Finally got photos of my chimera! I'm trying to find another for sale for crossings. Or maybe offspring as people don't want to part with them.   Here is the 36 gal, mostly planted. EBB and metallic galaxies going in here today, for now. First scape. Tried a bunch of rocks to no end. Lost most of the slope. I think primordial was achieved though. 20+ plants, won't go into them unless someone asks. Been hitting them with gentle light, co2 and ferts. A ghostie just cuz.   Red onyx are gorgeous and gregarious shrimp.   Still haven't got a good photo of the emeralds and I'm sure everyone knows blue diamonds.   I'll go hunt up pics of the shrimps incoming in the future so we can compare them to actual shrimps down the road. Adios

      I don't keep Sulawesi shrimp. So if i buy the ingredients for it, they won't get used and will be a waste of my money. Hope you understand. If you still want to try making it look for  Calcium Chloride Dihydrate  Magnesium chloride hexahydrate  Potassium chloride    For Neos, you replace the Calcium sulphate with Calcium carbonate completely. So the formula will look like this ... Calcium carbonate CaCO3 60gm Magnesium Sulphate (Epsom Salt) MgSO4 35gm solubility of CaCO3 is a lot worse in water compared to CaSO4. The acidity in RO water will help. Cold RO water will help it dissolve more too. The CaCO3 needs to be pounded down as fine as possible to help it dissolve.

      Do you think it would be possible if you could help by remaking one for sulawesi shrimps? and for neos do i add calcium carbonate and calcium sulphate or just use 10-20g of calcium carbonate?
