Works shockingly well I originally assumed this would be a scam, but I was super curious and wanted to give it a shot. I bought one a couple of years ago, but didn't have time to start up a tank til recently. Now that it's cycled and I added a couple of clowns, the filter floss gets super nasty in like 2-3 days. Any other tank I had, it took 1-2 weeks to change color. Only downside is I have to buy more filter floss regularly, but it's not really a bad thing, it just means it's working much more efficient now. I'm surprised big reefing channels haven't done reviews on this product.

If you struggle with water clarity you need this product. Extremely fast shipping to get the product. It was very well packaged also. So obviously when dealing with water clarity everything takes time. I installed the unit at roughly 8pm and the same time the next day there was a notable difference in the clarity of the water. I am using it in a 90 gallon cichlid tank with a sand bottom. Two of the fish are habitual diggers and are constantly turning over the sand so I have had to deal with cloudy water as they release sand into the water column. After roughly a week of use my water is very close to crystal clear and I highly recommend this product for anyone dealing with cloudy water.

Doesn't seem to do much in my 75 I have one in my 30 gallon and it works great. I just bought this for my 75 gallon and I'm not seeing much of a difference at all. I have left it in for 3 months now to give it a chance, but no luck.

Simple and mighty I know the benefits of blue light.I feel better knowing that the addition of that protection will benefit my tank.

I had very little success if any I had very little success if any. I added a UV Sterilizer which cleared my cloudy aquarium in fast order. I have installed the unscripted on another aquarium as sort of a trial run and will watch closely for results.
