Thread: Water quality?

  1. Default Water quality?

    0 Not allowed!
    Hi guys,
    Yesterday I had two MTS hitchhike into my tank (thanks to everyone on here who helped me identify them).

    I did some reading and found out loads about them but now they've got me panicking. I read they only ever come out at night and if they crawl up the walls during the day its the sign of a serious water problem.

    Well one of mine just crawled halfway up so I grabbed my API test kit and checked my water and my nitrite, ammonia and copper are 0 and my nitrates are between 0 and0.25 (closer to 0).

    I did a partial water change anyway but should I be worried?

    Nitrates that low would freak me out, my plants would be in serious trouble.

    MTS crawl out of the water if you're in real trouble. Little ones crawl up my aquarium walls quite often in the morning and late afternoon and I assure you, my water is just fine.Don't forget these guys eat algae and on your tank glass there is quite often some algae.

    Thanks talldutchie thats really reassuring.

    I thought the lower nitrates were the better? I have plants in my tank but I also have shrimp so I try to keep my nitrates low. Am I doing too good a job lol.

    Well.. lower nitrates are really good for your lifestock but nitrates are also important building blocks for your plants. If you have these chronically that low you'll probably see very slow growth.

    Another possibility is that you've stocked low and planted well and have enough other nutrients in which case your plants can use up pretty much all the nitrates

    Personally I try to keep 'm between 5-10ppm.

    I hope its the second one. I have only got 20 fish in a33 gallon/120litre tank and I picked them all based on hardiness and low bioload. My amazon sword is huge too so maybe I'm actually doing something right lol

    Echinodorus are nutrient hogs so if yours does well it's got enough to eat.

    Yea, I have been at 0 nitrates for months... but that is a heavy planted tank with multiple nitrate hogs
