Ph Is 6.4?

  1. annaberg1067 Member Member

    I have a 45 gallon tropical tank and I just did a wc. The pH is usually 6.8-7.0 but today it is 6.4. Is this concerning and should I do anything about it?

    What is your KH?

    I would get a KH kit then. But don't get the test strips as they are unreliable, I would recommend API GH and KH Test Kit (liquid kit). It's likely that your KH is low which can result in pH changes.

    Also, you nitrate is too high for your fish. What's the nitrate of your tap water?

    OK. My tap water is 0. I don't really know why but my tank has always had nitrates between 40-80, like it's never been below that.

    What's your water change schedule?. What's the stock of your aquarium?

    How often do you do a water change and what %?

    There's nothing inherently wrong with softer water as far as I know some tannins can actually boost fungus resistance in fish. It also triggers spawning in some as rain water softens water in nature. It depends on what you're trying to do but most fish are fine a little below neutral. Africans of course like hard water
