sand bed is about 2" deep
tanks been running for about 3 yrs
For water changes I get water from AD (salt)
For top off I get water at the windmill by pollys pet
I add a buffer
Don't think I'm over feeding. I feed 3/4"x3/4" square food.

Seems like the more I try to get it out, it grows that much more.
Not bad just looks crappy.
