I do regular water changes of about 3-4 gallons of water every 4 days. My tank is 90 gallons, and has approx 100lbs of live rock. I use a baster to blow out detrius from behind rocks, and the light smattering of sand on the tank bottom. I have place the live rock so as to trap as little sand as possible below it to aviod dead spots. My question regards the turkey baster. When I use it on the live rock I get alot of fine detrius coming out of the holes in the rock and from the little crevices in the rock. This will cloud the water for at least 15 minutes before the filter clears it all up. I am concerned about how much of this fine particulate 'sand' like detritius comes out of my rocks. Can anyone offer any explanation?
