lowering nitrites and nitrates?
i need to know how to lower the nitrates and nitrites without useing cemicals.

i have a 55gal freshwater tank, just lost all of my fish. the tank has only been running for about a month. it was previously set up at another house, i just transported it to mine with the fish.

Doing series of water changes will do the trick. Start with fishless cycling. Do not anymore try to use fish to cycle the tank to save time and money.

i didnt try to use fish to do the cycle. the fish came with the tank. they were very old fish. had been in the tank for around 10 years.

Could it be that they were all sort of senior citizens then? Moving could have been very stressful for them. It would be interesting to find out about fishes' life span.

I used to have an ancistrus who died at the age of about 14-15 years old. And an angel died at ten. His partner is alive and very active. It is very sad that he is alone but he wouldn't accept any other angel - friend. :cry:

I do suspect that it was the quality of the water at some period of time that killed them. Because a pearl gourami, about 10-13 years old also went with them at the same time. It was like a plague. :cry:

Now I am aware that I have to take good care of the retired folk!

ok, so i got the nitrates down, but i cant get the nitrites down. any suggestions without using chemicals, and is it safe to put fish in with the nitites around 2ppm

No! Don't add fish with nitrites that high. What are you using to cycle your tank? Did you read the sticky on cycling? Great info there.

tcr03 05-05-2007 04:40 PM

im not using anything to cycle the tank. i had some fish in there, but they passed.

You need to get your tank cycled before you add any fish. There's a sticky on how to do this at the top of the forum. Since there were fish in there, the good bacteria will start to die off if they don't have a source of ammonia. Have you tested your ammonia level? What was your nitrate level?

did you read the first post. the fish came with the tank. it had been running for 10+ years, i just moved it to my house. the amonia spiked, then nitrates, now nitrites. are up. i think the nitrates are around 5-10 ppm. amonia is back down to 0. i have ghost shrimp in there now. they didnt die with the fish.
