Hello all. This is my first post here and I am hoping you good folks could help me with my DIY waterfall scrubber idea. I have had an aquarium of some sort in my house since high school, but I have only ever run a sump once so my plumbing ability is not that great. My tank is a 95 gallon running sumpless and skimmerless for about 15 months. I made the mistake of buying my live rock from someone that was taking their tank down. I should have known better. It sprouted tons of macro algae, bubble algae, and what I think is turf. Aside from the algae growth I have been very happy with the growth and health of the corals. I have 8 fish and I feed about the equivalent of 2-3 cubes a day if you factor in feeding my corals. This is a recent photo of my tank: If you look in the left side of my tank you can see the HOG scrubber that I added in the hope of out competing the macro growing in my tank. I think cost wise I would have been better off building my own water fall scrubber or buying the turbo! Here are some photos of the harvest I got from the HOG. This is 7 days growth: It took me about 3 months to get to the point where I am harvesting this amount of algae growth. I posted over on the other forum and SM recommended I purchase another HOG or one of the others that he has for sale. That led me to do some more research and I found this forum. I thought my harvest was good until I saw some of the photos of the harvests from waterfall scrubbers. I have a cabinet beside my tank that I could use to plumb a scrubber. My idea is to use my ehiem 1250 externally from the cabinet with the input plumbed about 2" below the tank surface and then run a side drain from the scrubber through the cabinet back to the tank. Will this work? The drain would have about a 2 foot horizontal run before dropping into the tank. I appreciate and ideas and advice you all could share with me.
