For the past 2 months I have had the pest macroalgae, Briopsis, growing in my tank and it is starting to get really bad IMO. Now i know the only sure fire way to get rid of this stuff is to raise my magnesium levels to at least 1500 ppm. But I have an SPS dominated tank and raising the magnesium too fast or at all could kill them all off. However, I have nowhere to put them while raising the magnesium levels. So I have a 100 gallon tank and a 30 gallon sump and my question is how to raise my magnesium levels slowly enough so that it does not wipe out my Acros? (as far as increments go.) i.e. Should i dose magnesium once one week and then wait 3 or 4 weeks to dose again or what? Please leave your thoughts on this as all will be greatly appreciated!
