I just hooked up the Eco-Aqualizer about 12 hours ago. I know it sounds like snake oil, but I decided to give it a shot. Today really sucked though because one of my Crocea clams died for no apparent reason this morning. He was fine last night and next thing I know my crabs and nas snails were inside of it and it was gutted. I went to install the Aqualizer and my clam was dead and now my green hair algae just freakin bloomed again. I've got 25 gallons of water mixing right now and I'll do a water change in the morning. Anyways, I'll take some before and after picks to see if this thing really works. They claim you'll notice a difference in 48 hours, but I'll study it's progress over a month.
