Hello, I am interested in building (or buying) an algae scrubber for my 90g fowlr tank (reef someday). I purchased the tank used and I would like to convert the current bioball drip setup to house an algae scrubber, if that is feasible/advisable. I am interested in getting rid of the bio balls as I have done some "process of elimination" over the past few months to determine that they are the culprit that has been causing my high nitrates/phosphates. I have been slowly adding marine pure in place of the bio balls as I remove them as was advised by my LFS. With all of that said, I am not exactly sure if this is feasible and if so, how to go about plumbing. I've attached photos of my setup in hopes that some advice can be provided. My husband and I are both music teachers, so we don't know much (anything) about plumbing but I'm in this for the long haul and willing to learn. Right now, the water comes down from the overflow in the tank via flexible pool hose that hooks up to the drip/media pad filter and trickles down to the bio balls, then is able to be taken up by the skimmer and return pump. I'm not sure if any of this is ideal or what. For what its worth, maybe nothing, I also have a uv filter that appears to be plumbed off of the return pipe and I've just replaced the bulb this past week and just shut it off after running for a week. I am not sure if i could unhook that and just use its plumbing or not. Forgive my vague description of things, I have been studying everything for months but I still feel like I know very little!
