brown substrate

[dancingpig]

I posted a thread a week ago regarding brown algae (diatoms) growth on my live rock and substrate. Well, thanks to the addition of some snails and hermits the live rock appears to be on its way to being clean. However, my substrate (crushed coral) continues to foster this annoying algae. How do I get rid of it? Recently I have been resorting to stirring up the substrate with my hands in an effort to break up the algae, but this is only a very short term fix, I would really to get rid of this eyesore in my tank, any help would be great



75 gallon
1 cpr bakpak, 1 seaclone, 1 HOT magnum, 3 powerheads for water movement
dual bulb VHO (actinic, and daylight)
70 lbs live rock
various polyps and mushrooms
9 in. volitan lion, 5-6 in koran angel, 4 in. purple tang
I only feed the lion twice a week, and I feed the other two a half cube of frozen a day. (spirulina brine or emerald entree)
water changes of about 12% every two weeks with distilled h2o, should these be larger?

Patience. The substrate will probably never be bright white, but the blooms will fade and it won't be brown. This will happen once the nutrients and the critters/bacteria eating the nutrients come to a balance. Continually tweaking, stirring and fiddling with a tank will make this take way longer than just letting it go.
