Sand filled with crap, literally!

[Slammed01]

I have some hair and scarce red algae. Well I think my sand is filled with crap, I gravel vac this everytime. I scooped q bunch out and think the deep 2-3" sandbed might be the cause. Should I scoop out as much sand as I can until say 1" or so? ?

That's why I went bare bottom. My tank has been much better ever since. If I was to add sand again it would only be a thin layer and I would vacuum it often.

I'm switching tanks and plan on using live sand (shallow sand bed this time) and mixing fresh water. I currently have a 46 bow and want to go with a 54 corner with sump. I may use my friends 29 gallon temp for my 2 clowns and goby with shrimp.

I have green hair and cyano on my live rocks, should I sell with tank or would I be safe giving a good scrubbing and reusing and maybe cooking a few?
