![]() Well, yes and no. Kinda. The thing is, I don't think you need sand at all, and if you use it, is 2 inches bad where 4 inches is good? If so, why? If not, why not? Don't worry, we'll get our own thread going

![]() is it loose clumping or hard clumping? loose clumping is usually from sticky biofilms from excess dissolved organics,hard clumps is usually calcium carbonate binding
