SOBAKEN Reef Octopus LR-200 8" Light Reactor

I bought this some-place else (but using Amazon as the purchase). I have a 90 gallon salt water tank. I did exactly what Reef Octopus says to do on their videos. Using Chaetomorpha in the canister!It worked exactly as they said it would. Within 2 weeks my Nitrates went from almost 10ppm to 0ppm. This thing works and no need for a sump.Completely removes the need for water changes!I bought the LR-200 which is suppose to be bigger than what I need for a 90 gallon but why take the risk. Just better to get the larger unit.EDITED: Just cleaned it my first time and it was difficult. They really should have put a double tap valve connecting to the lower end of the unit and a shut off valve connector on the top. This way you can take it out from under the aquarium to be cleaned.NOTE: This thing has to have its Chaetomorpha cultivated (meaning remove most of it) monthly. This is REQUIRED because it grows VERY FAST! But doing this is much easier than a water changed. I added my own valves to the unit so I can clean it up and take it out easier.This thing does work fantastically! I just can't say it enough!
