I can get it for 8 bucks a bag.....which is really cheap up here. Also, should I be adding sand to my tank after a period of time? I read somewhere about LS eroding and losing it effectiveness after a period of time.

Not sure about that, but as for sand, I top mine off every year or so. You will be able to see if it erodes a little.

I've never used it. But it would be good to hear from someone who has and get their take on it.

I've never used any of that sand.But I dont think it would be bad for your tank.
