I am thinking about removing the fuge and sand from the center section of my sump.
If you decide to remove the sand I would strongly advise you to isolate the refugium first. Then remove the sand and rinse the fuge clean before refilling it. If you don't do this you run the risk of stirring up some really bad nasties that are trapped in the sandbed and could do more harm than good.
Just my two cents.
Oh yeah I know. I would shut off my sump and remove all sand and water. Luckily the sand is not that old. I just replaced it trying to kill off CCA.If you decide to remove the sand I would strongly advise you to isolate the refugium first.

I am also having more algae building up on the glass, dont know if this is from the MB7 or not. I am dosing 1 drop daily and 3 drops of vodka.
I am dosing the MB7 as per the directions for my tank its 1 drop daily or 5 mls weekly. I do daily as I feel it supplies a more constant supply of bacteria. 3 drops of vodka is .1ml and is my maintenance dose, I had issues when dosing more vodka. PO4 is 0 and NO#3 is 3-0 ppm. I do 5% weekly water changes or 5 gallons very week.
