I recently was given a recommendation on upgrading to this skimmer. The HOB type. I have a CBR BakPak 2 right now with the bio bale chamber. The reason I am looking to upgrade because I get a lot of brown all on the glass and rocks and I am thinking that this is because of high organics and phospates. But the water is clear. When I looked to see the price for these skimmers, $500. Is it worth is for a small 55gl? Has anyone ever heard of these skimmer or have one? Any insights would be helpful!!
