Osmocoat seems to the best long term option, no cloud, no tacky pulling up pumice gravel later on, no mixing etc, if you want a base layer, and want nutrients, this is the way to go.
ADA aqua soil is a good all in one product, there's little need to add powersand.
This works on it's own,I suppose as a base layer if you like 2 part soils, buyt unless you use the top sand for aesthetics only, then might as well just use 100% ADA AS.
I see no good reason to use ADA power SAND.
I know aqua soil came out long after power sand, guess they wanna keep selling stuff they already have but after a month or less, there's not much left, and then it's a tacky mess waiting to happen. I like to reuse sediment later, ADA As last a long time, drops in N, but that's about it, the rest stays put, the powersand is all gone, everything, in less than a month or so.
It's your money getting washed away :idea:
You know I'm not anti ADA either, I'm promoting one, but not another.
It's what I use personally too.
