I've been using 100% akadama with great results, so you dont have to have anything under it. It also depends on what scape you are going to have as very deep areas probably won't be reached by many plants, and what plants you intend to use, things like glosso and HC have very shallow roots so wont get to much deeper than and inch or two. If it were me and I def wanted/needed something underneath I'd get a cheaper substrate like tropica which is designed to be a base layer. That said a shallow layer or AS wouldn't cost the earth on most tanks, but you would have the initial NH3 spike to deal with.Antoni Dimitrov said:I have been reading a lot last few days and I still can't figure out, what is the best base mix for Akadama:
I've managed to get fairly steep slopes from it. Say perhaps 30 degrees or so.aaronnorth said:How is this stuff for sloping? I know aquasoil is very good as it stays in shape pretty well.
There's a chance the tank could be up to 5x2x2' so I want it cheaper than that!Nick16 said:i got mine from ebay mate.
