Two Questions

[diamond]

I have a 75 gal Reef with about 12 corals and polyps (bubbles, mushrooms, green and yellow polyps,cup, open brain, etc.) and 6 fish, (maroon clown, percula, basslet, coral BEAUTY, falco hawk, etc.).I also had a fairly decent sized colt that was flourishing, but, he suddenly started fadig and finally got so down I removed him so that he wouldn't damage anything downstream. Are they succeptible to some mineral deficiency or disease? Eveything else is lovely and healthy. (Knock on Wood)Number 2.Red slime algae. I'm fighting it all the time. All water tests are where they should be. I feed twice a day so I don't think thats it. By the way. The slime is on the sand mostly so was well awy from the colt.

How long has the tank been set up?How long you leave your lights on?It could be a combination of a few things rather than just one.Over feeding and a long day time could cause algea build up.Not to mention new tank build algea quick.Are you using tap water?

My tank has been up and running about 6 months. I have two powerheads plus the sump return pump so there is plenty of water movement. Lights are on from 10:00 AM to 8:00 PM. and I feed twice a day.
