Any Opinions/Ideas on Rescape Substrate?
I am looking for some advice prior to a long awaited rescape. I currently have MGOPS capped with blasting sand. I started my tank on this approximately two years ago and since I have lost slope and there has been mixing of the white sand path and black sand I put in incorrectly (live and learn). I am also getting some dirt coming up when removing rooted plants. I have also gotten past the sulphur bubbling up from the anaerobic areas which is nice.
My question is what do you think would be my best bet to do with this new substrate, or what would you put in if you were doing a rescape? I would like a larger grain for ease of syphoning along the bottom but don't want to lose out on the benefit dirt will provide my rooted plants. I am also concerned about losing my beneficial bacteria although I am running two multistage canister filters.
I am currently selecting plants for the scape which will require a higher demand, my CO2 is back up and running with EI dosing and I am adding a second two bulb T5H0 fixture. This is all on a 75G with a moderate stock of fauna.
Thanks in advance for any advice.
