Nitrite high- Ph low
Hello all

I have had my 55 gal. going for about a 2 months. I keep testing with API FW master test kit. doing 2 water changes (15%) a week. but I still get a Ph of 6 and a nitrite level of 5. everything else (amm., nitriate, ) has trace amounts. temp at 75-76. I need some help.

What do you have stocked in this 55 gallon?

I would consider 5ppm a trace amount anyways(not saying it can't do harm, but that it's not a lot), so what exactly are your ammonia and nitrate reading?

To help raise pH I know adding crushed coral to your tank does the trick, I'm not sure how much though, I'm really only interested in lowering my pH at the moment, so you'll have to get help from another member or do a little searching around yourself for help with that, sorry!

P.s try water changes of like 25% and see if that does the trick, in 55 gallons of water, 15% isn't really a lot.

Your nitrites are 5 (not nitrate)? Nitrite level of 5 is very high and dangerous for your fish. Was your tank ever fully cycled at any point?

Maybe check your tap water and see if there are nitrites in there. Did you cycle your tank before you added fish? It could be still cycling if you have been doing a lot of water changes, which will slow the cycle down. But don't stop doing them, and maybe increase the amount that you change because nitrite is still toxic to fish. That's all I could think of. Good luck.

I would say a tank thats been set up for 2 months its more then likely cycled? Well I should hope so at least.

I retested today and my readings are amm. .25, nitrate 5.0, nitrite 1.0 (its coming down). and Ph 6. at about 3-4 weeks ago everything was at or near 0 and Ph was 6.6. I hoping this was some freak spike but dont know why.

I'm stocked with
5 red eye tetra
6 cherry barbs
3 red glass barbs
3 tiger barbs
2 clown loach
2 live plants

also I'm thinking about getting a Bio-wheel letting it cycle with my old filter then removing the old one. any thoughts on the wheel and switching over.

i actually did the same ran my old filter w/ a new penguin i just bought. i hoped it would help quicken my cycle and i think it helped. the only thing would be is to make sure you give the new filter time to populate w/ good bacteria. when i did it though my bioload was much smaller so that could be cause for concern as your stocked already.

when i did it i kept both filters in for almost 3 weeks. at the end of the first week my cycle completed and i kept them both in there for 2 more weeks. just letting you know what worked for me.

Were you using any ammo chips or anything like that to keep the ammonia levels down? I noticed that when I took them out that i had a minor ammonia spike but nothing like you're seeing.

It doesn't look like your OVERstocked, so I don't know. How are the fish reacting?

What are your tap water parameters?

cavediver 07-22-2008 08:08 AM

I checked my tap water, the readings yesterday were very high to max high on all parameters. going to LFS to get water from them. I'm want to use my RO system at the sink but only get 3 gallons at a time.
