Hi

I had a problem in my tank since i started my tank up, just over two months ago. Every other couple of weeks i will get high ammonia and nitrite, and i am scared now that my frys will die there are only day old. My ammonia is at 6.0 and nitrite is 1.0.

Please help

did you cycle your tank before you put your fish in?

i'm new to this but i think you may be able to have high ammonia from over feeding.

Quite frankly, I'm surprised your fish are still alive with levels that high.

What size tank? How many of what fish are in it? What filter do you have? How often & how large are your water changes? Have you done anything with the filter media lately (washed it in tap water or replaced it)?

For the time being, I suggest doing a series of 50% water changes every couple of hours until you can get your ammonia & nitrIte below 1ppm.

One of my frogs has die today. My tank is a 14gallon tank. With 2 goldfish, black widow, 2 guppies, 2 silver tips, 2 swordtails, 1 frog and 17 new fry. I think it maybe cause by the fry this time, i do tend to overfeed sometimes. I have a fuval 3 filter. I have not touch the filter media, but the now i am treating my tank, because i have parasites.

I have tried doing water changes every couple hour the last time, and i was doing it all day and the ammonia and nitrite stayed the same. I done a 50% last night.

Wow! Your tank is WAY overstocked and that's what's causing the high ammonia & nitrIte.

2 goldfish (assuming they're fancy, not commons or koi) need at least 20 gallons, but 30 would be much better. For the tetras, guppies, and frog you need to alot at least 2 gallons per fish so that's 12 gallons not counting the fry. And the swordtails need 4 gallons each. So basically to house all those fish (not including the fry) you would need at least a 40 gallon tank. The only solutions would be to either buy another tank or get rid of some fish (I suggest the goldfish).

The fact that your ammonia is almost off the scale and your nitrItes are also well into the toxic range indicates that your tank is indeed overstocked. I'm not exagerating when I tell you your fish should all be dead with those levels. BTW, what's your nitrAte reading?

I'm guesing your fish are still pretty young. When stocking a tank you have to consider the adult size of the the fish. Assuming those are fancy goldfish (round bodies) they will get about 8" long and almost as tall & wide. Your tetras & guppies are all going to get about 2" each and your swordtails will be about 4".
