Aqua soil powder type out of stock, best alternative?
Hey guys so ive been debating on if i should go with a mini M or mini S. I really wanted to but obviously being in college the bank account doesn't justify. So i'm going to go with a Do Aqua 20c and try my luck with that and a desk light. I'm planning on ordering everything monday, i was planning on getting aquasoil powdertype but realized its out of stock on the ada website and also the ada shop.
Is there any other place i can get this?
Will the standard type grain size be too big for me?
Whats the best alternative substrate i can use?
Also will i need a heater for a 2 gallon tank?
Thanks for the help!
