im just freeking out thanks to the fact i have some older fish in there...none of them seem to be struggling...but the nitrites are DANGEROUSLY high despite water changes every day.
im half wondering if my test kits old though because as i said, readings say dangerously high but the fish arnt shwoing stress signs...
the kit im currently using has my tank at:
test kit is generic test kit from walmart box is destroyed dont remember brand...
NO2: 10.0 ppm
from the tap:
After 24 hrs from tap
tanks is crystal clear, no cloudyness, runing a whisper 30i with foam and carbon and an undergravel filter. seeded beneath undergravel and in whisper filter with gravel from established 10 gal.
running a "bubble curtain" and undergravel airstone for filter.
Plastic plants, faux aquarium aproved rocks, and a large OLD peice of driftwood thats been in my tanks for many a year.
gravel is washed "river rock" aquarium gravel.
tank was set up for 2 years about 8-10 months back, with same undergravel fliter and driftwood...all else is brand newnew.
no chemicals were used in the tank before setting it up (no bleach ect)
tank was reset up a while back, cycled normally with amonia and no fish, all readings good...added 3 serpeas and rainbow shark, 1 serpea died...did regular water changes of 10% daily...readings remained normal.
added 5 zebra danios, all but one died within 2 days. all bodies removed, but thats when nitrites and nitrates started climbing...
25% water changes daily for past week and a half/2 weeks almost and nitrites still kept climbing...
hit 10.0 today and im worried.
fish are showing no signs of stress and no deaths in 2 weeks...
have another post here about the situation, but im at a loss...
ordering a new test kit asap as the one i have is old...
mum wants the tank set up for the grandparents comming out at the end of aug...ive got a month to figure it out...(fingers crossed its a bad test kit and im worrying for no reason)
i just cant figure out why the nitrites are so high!
