    i just bought crushed coral yesterday ,plan to use as ph increase method, but it still big like 1cm diameter, should i crushed it more smaller? It is better to put inside the filter or hang on side of aquarium?

    Yeah that seems a little big. I put mine in a mesh bag used for ceramics or such and add it to my filter.

    I put mine in a mesh bag as well. The bag I got was a little rocky fine grain...not sure if that makes sense.

    The ratio I recommend should be 1 cup to 40 gallons. You can do less if you want to increase a little bit. I had a 6.0 pH. One cup brought it to 7.4ish.

    Have you tried putting it in the filter? The way I see it is either use it as substrate or put it in the filter do water runs through it and not just around it.

    Try putting into the filter and see if that increases it.

    You don’t need to remove something, just squeeze it in a tray. The flow rate may be a little less but you’ll be sure waters flowing through it.

    If the pieces are to big to fit in your filter - make the coral smaller with a hammer. Quick fix!

    Coral isn't an instant fix. It takes a while because it has to slowly dissolve. It will keep your PH stable by raising and stabilizing the kh/gh of the water.
