I have a large pail of lava that I would like to use up and I am wondwring if I could use it in the bottom of my AC. I only jave filter floss in there right now and when it is changed its usually only the top 2" that is dirty so I figure if I put lava rock in the bottom and half the amount of floss I will not only save on floss but also keep a constant supply of BB in the filter.
On a side note I am hoping that scrubbing the rock with a stiff brush and hot water is the only prep that is involved
