| Re: Substrate decision My sand bed will be between 5 and 7 inches. Jim, that's the reason I bought the mixture. It's going to be all mixed together and it should prevent any kind of clumping. But the mix should be to the liking of a bunch of different sand living critters. All of the sands that I bought are Aragonite and should provide decent buffering and the aragamax will help to boost it just a bit more. I actually haven't had an issue with maintaining an 8.2 - 8.4 PH but I wanted to be sure I didn't after bringing the 450 online.
Oh yeah, and if I was planning on a DSB and the nitrate reduction they provide, then wouldn't you want the sand packed together as tight as it could be to protect the bacteria that develops deep in the bed? It should have very little flow deep down. At least, that is the way I understand for them to work.
