[QUOTE=gravereaper0;2381013]I've made the same mistake and listened to the girl working at pet smart and put a 40lb bag of argonite sand into my gold fish tank. D'oh!
But all is well my ph went from 7.5 to 7.6-7.8 and it looks real nice.
I take the point but i believe if you keep good cleaning, filter and PWC
routines, you won't have any issues. I have kept sand for years, mainly in goldfish tanks and have never had any problems. I always use cheap play sand. Your tank looks great by the way.....
