Thank You Jgentry! I'll be moving my maculatus into a 90g in a couple of weeks and I didn''t want to have to remove all of the substrate I already have in there for crushed coral.
There have been several breeding reports of menerambo in softish water with neutral ph so I think you will be fine. My Maculatus have been very tough and durable, they do not seem to care much as long as the water is clean.
