Ya ive seen that but i want to go with something that look great. On my 29 I have a wet/dry and my nitrates were always going up to 20ppm in a week. I went to Alamo and talked to Chris and he sold me just a acrylic box. He cut me two holes for some bulkhead and I put in two pieces of plexy glass one with baffles. It didnt fit under the tank so I put it behind it. I tested it yesterday and it read 0 on everything. I like that set up, but just wanted to know what was the best filteration out there, thanks
