I am running chemipure elite, purigen and filter floss. I have one IM media basket set up on one side with the filter floss on top, then purigen, then the chemipure elite. I don't have any other filter media on the other side. I am doing 3 gallon water changes weekly. I have 25 lbs of live rock and I have live sand. The tank was set up in April so it is fairly new. The only thing I am not running is a skimmer because I was undecided which one to buy. I have 2 clownfish and 1 sand sifting goby and assorted snails. I have cut down on feeding my fish. I use only RO/DI water. Would the skimmer help to get this under control? Any other suggestions?

How long is your light cycle? What's your water tests show?
You could try no lights for 3 days. That's always worked for me...but if your phosphates are high...it'll just come back. How often do you feed?
Skimmer will help some...not all.
How often do you change cpe?
Sorry for all the questions..you could try to post same in water chemistry forum..
