I've transferred my fish over to a new 185 that has Aqua Soil in the bottom. In old tank, I had regular gravel and lots of Malaysian Trumpet Snails to work through the gravel keeping it from clumping and developing anaerobic conditions (at least that was the thought some years ago).
The Amazonia AS seems very light so not sure if the tank will benefit from MTS. Will MTS benefit my new tank? if not I'll leafve them out
