I transferred my corys to my 75g, in doing so, I reduced the water level to catch the fish easier. When refilling the tank I stirred the substrate a bit, a tremendous amount of mulm. I'm trying to figure out what caused it and how to prevent it. It has somewhat large ragged substrate, and a small HOB filter (Aqueon 20 I believe). A lot of the mulm looks like dead algae. I'm going to relocate the tank and I ordered an Eheim 2211 and a small UV unit. I have algae issues with the tank which got a bit better when I changed the light cycle to 2 2hr periods. As I don't like the substrate I may change it for a smoother and finer one. As this is my quarantine/hospital tank plants are limited to some Java moss on wood.
I would like to know what, if anything, I can do to minimize the mulm? I'm thinking that a gravel vac might help, and I'm hoping that a lot of the problem was the algae problem that I had. When the corys were in there, they were fed 1/8t nano bits sinking pellets 2x daily (7 corys).
Any thoughts or suggestions welcome.
