Any suggestions for cleaning algae discoloration off hardscape rocks?
The balance in my tank is fine, I've got light/co2/ferts pretty well handled, but there is residual coloration of my hardscape rocks. I'm not sure if I should just try a few direct doses of hydrogen peroxide, glut, or add just enough salt to my tank to help keep some nerite snails alive. (I've never had one live more than a week, and all I can attribute it to is that they come from a brackish environment and my tank has no salt).
Is anything known as a good means of cleaning rocks up?
Honestly? Clarisonic. I even clean leaves with clarisonic "luxe" sensitive brush head! It oscillates and does not just rotate, so the "luxe" heads are safe on plants. We are talking butterfly-kisses gentle. Mechanical oto haha. Clean then water change. Four levels of intensity plus "turbo" mode haha. Rougher brush heads are good for glass and rocks.
Obviously I have dedicated brush heads for aquarium, that I do not use on my skin.
Don't judge me haha. You are supposed to toss the brush heads after three months of use and buy new ones, so I decided to recycle them for cleaning aquarium instead of just throwing away.
Going out and buying a new clarisonic for an aquarium is dumb since they are so expensive, but if you already have one, anyway.....
