Has My Substrate Run Out Of Gas?
Question - when I set up my 75G 2 years ago I used 50% gravel and 50% Red Sea "Flora Base" Substrate.
Lately, however, my growth has seemed to slow way down. I am wondering - has my substrate run out of gas? Should I consider supplementing?
I have been to ADA and you can spend $1M on substrate supplies there....any other ideas?
