Hoppy, if I used colorquartz, should I add anything underneath it, like laterite or peat? Would I need to use root tabs to fertilize things like cryptocorynes and anubias?
Larry, maybe they've changed it, or maybe you're using amazonia II? I used the first type of amazonia and I bought it a few years ago. It seems that there are a lot of "silt" particles in the aquasoil. Even when planting stem plants, once I get past the very top layer I encounter some mud. I'm sure the plants love it, and I can vouch for the fact that they grow great, but it makes rearranging things a pain because once I uproot something big, I can't see anything I'm doing. Rearranging stems isn't so much of a problem because they aren't heavily rooted, but I have a hard time with anything like crypts or swords, or rearranging any hardscape that's partially under the soil. In addition, when I first set up the tank it became so cloudy that it literally took over a month to fully clear, even though I performed several water changes and was running an ehiem canister filter filled with mechanical filtration media. I've read of others on this forum having similar problems, but others such as yourself don't seem to have issues.
Maybe it's possible that some bags just have more of these silty particles than others, since it is possible to break aquasoil up in your fingers, maybe rough shipping or other factors could come into play? Who knows? I'd still use it again for any stem plant intensive tank, but my goal in this one is to have more well rooted plants like crypts. Not a bad product, just my experience with it.
