Low kh?

    So I finally got my kh/gh test kit yesterday, the results are..
    Kh 3-4 drops (turned ever so slightly yellow with 3, but not completely yellow until 4 drops)
    Gh 7 drops
    Using the api liquid tests.
    My ph is stable around 8.

    Since I have live bearers and snails I would like to raise my kh. Will adding crushed coral to do so also raise my ph? Because I feel like it's plenty high as is....I really feel like I should get that kh up though for my snails in particular.

    Yes put some crushed coral in a mesh bag into your filter. Then test again tomorrow.

    That's what I'm thinking. I just worry it will raise my ph too much :/ I suppose I could try some and see what happens. After some googling that seems like the best option. I'll probably throw another cuttlebone in there as well.

    The crushed coral has raised my kH but not my pH...at least not yet. It's just keeping my pH steady at 7.8...or buffering it, I guess is the term.

    What's the pH of your tap water? The KH will only buffer your pH not raise it, unless you use aragonite-based substrate. Or ones that have limestone etc.

    Ah, good to hear! That's what I'm hoping for since my ph is already pretty high. Thanks!
