I didn't know you shouldn't be vaccuming your dsb. I thought all that stuff that was getting sucked up was bad stuff... never again. oooops, no wonder my tank was taking so long to cycle...
The gravel should be removed. If not, being larger it will eventually rise to the top of the bed and essentially block it from working correctly. A quick search on here or Google for "deep sand beds" should give you more than enough reading to fill the next few nightsCan I just add the dsb to it? I am getting the dsb at my lfs, so it is already live sand. By adding it to the gravel, am I going to disturb anything? e.g. will it make the tank start its cycle over again???
