Trying to decide between soil and EC
I know there are a lot of threads about these two types of substrates. I canít make a decision. A couple of years ago I bought 8 or so bags of EcoComplete. I never used it but now Iím reworking my 75g to house Corydoras. I want a black, sandy surface for them. My intention at the time was to screen out the larger pieces and use the finer portion of the EC. Now Iím considering a soil base with black sand on topÖbut the threads Iíve read say there can be a release of ammonia initially when doing this. I need to be able to put the fish back in when this is done. Any advice? Any suggestions other than these two? Thank you.
