UV Sterilizer

[stephane]

Algea problem is only and only one ting. To much nutriment in your water.
UV will not export any nutriment but only kill free algea cell that live in the water

UV are sterilizer and will kill everiting that will came in!!! you have a reef and your water need need to be full of life it is the naturale cycle of your reef and the way marine life is. UV are not only useless but even break a lot of natural phenomen

If you have algea you have to export nutriment

good skimmer,polyfilter,water change,Use RO water only,caulerpa,hight PH.......

PS: medication are pita just like UV
