why are we running DSB and is it for the right reasons

[EmilyB]

I went with 1.5 and closer to 2 lbs per gallon of live rock when I first got into the hobby. I just saw some older pics of my tanks....and I never had nitrate or algae problems then.

I also jumped on the sand bandwagon.

Now I have a sandbed four years old that is just a shitload of crap. I purchased live sand every year for it, etc. I am in the process of replacing rock, and removing sand. I've never had the problem with an inch or so of sand in some smaller tanks. But none of those small sandbeds have been up four years either.
