well for the last 8 months i have been battling cyno and algea problems that have kiled most of my sps. i have a dual beckett skimmer that i had to adjust everyday to keep the water in the tube high enough to skim wet and it just didn't seem to be working right. so i have been looking at getting a new skimmer and they all recomend a high gph. then it struck me. my pump from the sump feeds the tank and the skimmer. there is a ball valve after the line feed the skimmer that has been open all the way so that i get the MOST FLOW TO THE TANK AND NOT THE SKIMMER.
i have now adjusted the valve for more flow to the skimmer and now i dont have to adjust the water level. also i am getting more and darker skim mate from the tank. the cyno is getting less and less in the tank so i am on the right track again. I HOPE!
