Aquasoil/Stratum break down
I'm strongly considering switching to either ADA Aquasoil (Amazonia or Africana) or Fluval Stratum, but in researching on this site I keep finding the occasional report of substrate breaking down in a year or less.
Ideally, I'd like to not have to tear the tank down for at least 3 years. Though I realize that nobody can guarantee that result I'm curious if anybody is having this kind of sucess with either of the above (or something similar).
FYI...my tank is a 38G Bow so it is on the taller side at about 21". Does the water pressure resulting from the tank height negatively impact these soils?
