I have a 38 Gal FOWLR tank with a single clown, 2 cleaner shrimp, 1 scooter blenny, 1 6-line wrasse, feather duster, pink tube worm anenome and the recommended number of snails and hermits.

I made a refugium for the back of the tank modelled after some of the hang-on units I've seen in catalogs. I have it mounted slightly higher than my tank and is fed on the output of a Seaclone 100 skimmer. I placed a few baffles in it, and the output is located onthe opposite end. It simply drains out into the tank via a through-the-hull fitting I picked up in a marine shop. It seems to be working well enough, but I have a few questions I was hoping someone could help me out with.

The dimensions are 20x12x4. I have about 3" of Fiji mud, with a smidgen of live sand, some live rock and 3 types of algae in it. Is this too much mud and not enough sand?
I'm guessing the gph on the skimmer is about 380. I am wondering if this is a fast enough flow of water? I'm worried about dead spots.
Also...I understand I need to have some janitors for it as well? Does anyone have any suggestions as to what type/amount I might need if so?

The overall look in the fuge is I'd say murky...the water is somewhat clear, but all the algae and such have a muddy look to them possibly from my moving things around but this led to my wondering if there is enough water movement through it.

Anyone with any ideas?

Thanks in advance,
Todd
