Hello everyone! I would like to know how often people blow off there LR to clean the detrius off? Then once it is in the water column does a skimmer remove all the particles, or should you run some sort of mechanical filteration? I came back from a vacation to find a nice algea bloom (bryopsis I think) covering my LR. To be honest the tank has been up for about year and I perform water changes about 25% every 4 weeks, but have not blown off my LR. I think by this time there is plenty of Phosphates to fuel this algea growth. This is my first salt attempt. Don't be to hard on me.
