new deep sandbed

[gotreef]

Gonna try a deep sandbed and want to know if I can add a 1/2" a week to the existing sandbed to get to 4" or do you think I should remove old substrate. Old stuff is coarse, maybe 2-3mm, and 1"-1 1/2" deep. New stuff will be oolite and like I said going for 4" plus. Now I've read and heard alot of the negative stuff on DSB's but I want to try and if I fail well so be it but I figure at least I tried. So what are the thoughts on the question I have. Thanks for any response.

Why fail when so many others have done so for you? lol

4" won't be enough....

If you decide to do it, make sure you read all of the literature, not just the ones that say how good a thing it is, but the ones that say how hard it is to set up and what not to do.

If you're doing a DSB...use a Plenum!!!
