You know, as someone switching
from dirt to aquasoil soon, I would really appreciate responses to the OP's original question.
@Jack2714, I haven't used aquasoil myself, but have looked into the differences between them and can't really get a great answer. Amazonia seems to have the best reputation, but is known for initial ammonia release. But people also seem happy with UNS Controsoil, Tropica's aquasoil, and Landen's aquasoil. It seems like most brands may have some variation in product from bag to bag, leading to some slightly irregular results with respect to nutrient amounts, buffering capacity, and how long until the balls start breaking down. Supply seems to be an issue right now with aquasoil, like we're seeing with many aspects of the hobby, but it's not an impossible challenge. I feel like Fluval Stratum has the worst reputation of the group (not to be confused with Flourite, which is inert) I wish I had personal experience to draw from, but that's my topline summary based on a lot of reading.
I will say I'm not sure I've heard anyone say that they have tried dirt and aquasoil and went with dirt. I personally don't regret starting with dirt, but it's madness to act like it's the obvious choice if you want the "best" tank. It has pros and cons, and I'm not sure what advantage it has over aquasoil if you don't have an issue with the cost and appearance.
