I treated the water in my aquarium with Herbtana and Artemiss for 10 days to try sort out white spot on some of my clowns.The skimmer was turned off for the 10 days. A 15% water change was done after the ten days and the skimmer turned on again last Thursday.Ever since then the skimmer has been constantly overflowing and I have tried adjusting the settings with no success.I added the usual weekly coral food (Fuel) on Saturday and pH buffer.Tank parameters are as follows:100 gallon, pH 8.2, Nitrates 10 ppm, Ammonia 0 ppm, KH 12.3,Alkalinity 4.38, Ca 440, Mg 1365.Temp 25.6. The skimmer is a Bubble magus .Any advice would be appreciated.Thanks
