How often should I clean the refugium?

get your nori at an asian supper market. Don't waste you money on live sand unless it's crawling with critters you can move some of the small life from your main set up to your fuge. I might not make many friends by saying this but, live sand IMHO is usually a big old waste of $. Your sand will be live sand soon enough as far as the bacteria goes and you're better off if you pick your own critters.

Make sure you check your ALK, Calcium levels, pH, and Phophate levels. These will all have an effect on the cyano problem. Also, where are your nitrtates currently at?

Post the test results after you know them. If you don't have the test kits the LFS will test for you.
 
Nitrates are around 15 still and I just did a massive water change. I also removed about 15lbs of crushed coral, especially in the back where I used to have some dead spots. Those are now being blasted by a maxi 1200. This nitrate is a losing battle. Although, the refugium algae seems to have taken it down from my usual 70+ readings. I just can't get it down to 0 and I won't put any sps or lps in there until it does.
Thanks,

A good idea also, try mixing the Fuge up a bit with a plastice rod of some sort if it is an Argonite bed. It may help you out some and feed your inhabitants, soft and stony corals. I have found this works well for any buildup on the subtrate.

Just my 2 coppers is all.
