    Hi there @Scottshark ! You could do 20% and above water change weekly.

    Cool...I was concerned that 40% is too much

    Yeah 40% is a bit too much.

    Depends on the tank size and bioload. I do 50% weekly on my 5 gallon betta tanks. That's the least I can do if I do the quickest bottom clean possible.

    The key is keeping your nitrate below 40.

    Keep an eye on your Nitrates...I try to keep my Nitrates 20ppm or below. As far as water changes I do 50% or more weekly.

    Yeah I agree, it really depends on the size of your tank.

    40-60% weekly is good, 20-40% twice a week is even better

    Honestly, since the beneficial bacteria live in your filter media you can do 100% water changes if you prefer. The main thing when changing water is to ensure that the pH and temperature of the water matches your tank.
