I am having the same problem lately. It did start when my skimmer overflew and that nasty stuff went into my sump.... I was able to get rid of it a month ago when a did two big water changes and I clean the back wall of my tank really well and turned the lights off for few days + reduce the ammount of food. I will do that again this weekend... It is not easy but you can do it.
I am feeding my fish with Jan's food since she started and my fish and I love her food! I must say that I feed her food every other day just because I still do pellets and mysis only...
I don't have problems with sandstorms... the only reason is because it easier for some coral to attach to crushed corals (srooms, etc..) but it is true after awhile it will start to settle down... I may try a bit to see how it goes.. Thanks guys
Is that Ok to put crushed coral on top of a sand Bed. Ah, on a established reef tank... I would like to add but not sure if I can do that. I must say not too much about a 1/2 in or a little more .
Jan , interesting posting I will be following this one cause I will be probably moving to FL in the end of the year and I am definitely bringing my 90 g system with me .
Btw if you need any help when time comes you can count with me
