Nitrates ??

    What causes my nitrates to keep being high after water changes? The tank is well established since Oct. of last year, param. 0,0,40-80, tap n03 5.0 . Did a 50% W/C yesterday, today nitrate back up to 40-80.
    40 long
    fish: 6 platys, male/female DG, 6 rummy nose, 6 peppered corys and 2 BN, lots of plants, driftwood and slate. Any ideas?

    on a side note why does it keep saying that my title must contain 10 or more characters, I had to add two question marks to the title just so it would take.

    Check the nitrate in your tap water, would be my first guess. Sometimes it can go up and down.

    Seconded. Test your tap.

    It says 10 or more characters so people don't type just one word and it differentiates searches, so you don't get 40,000 threads when you type in a single word.

    Do you have male and female platys?

    If you do, then there's a good chance you have constant fry coming. Those fry die either naturally, from stress, or from predation and pollute the tank.

    The fry pretty much get eaten as they spit them out, I do W/C w/vacuum weekly about 50% a week.

    Do you rinse your filter in tank water, do you have bio balls or anything like that?
  8. yukondogWell Known MemberMember

    No bio-balls, yes filter rinsed in tank water, going to try about 90% WC this weekend.

    Ok, hopefully that will help some. Maybe update us on what your levels are after the wc :)

    Did about a 90% wc yesterday and rechecked nitrates this morning, still a little high 10-20, did not clean any d├ęcor just vac. and filter.

    Since you have nitrates in your tap, maybe try some nitrate reducing filter media added to the hob filter... or you could put some more plants in there to help with it a little bit more.
