My tank is a 55 gallon. Substrate is Crushed Coral. Wet/Dry filter. There are currently 1 cleaner shrimp, 3 pepermint shrimp, 1 anenome, and some snails in the tank. 11 pounds of live rock. Water quality is good, with Amonia at 0, nitrites o, and trates at 0. I moved all of my fish out of the tank a few weeks ago into my quarantine tank. My Hipo tank came down with ich so I decided to treat all the fish with hyposalinity for 1 month. I recently replaced my 2, 15 watt lights with 2, 32 watts lights.
After doing some searching I found that the Red Slime is probably from to much phosphates in the water. Also found information on a Red Slime Killer chemical that you can buy at the store. Anyone used any of these before. I recently added about 5 gallons of tap water and removed 5 gallons of salt water to lower my salinity. It was creeping up. Could have to many phosphates in my tap water. Could also be from poor water movement. Probably should add power head to increase water movement in the lower part of the tank. Right now the Wet/Dry return in pointed at the surface area to move that water.
