12 Gal Long ADA powder
I am planning a 12 gal long iwagumi. I will have an HC carpet and plan on using ADA amazonia powder only. I will have 15-20 lbs of seiryu and I want to know how much aquasoil I need for room to have to nice slopes if I desire? Also will if I open a bag of aquasoil and play around with it and the hardscape how long can I leave it in the aquarium dry? Will it go bad if just sitting in the tank dry?
