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 have been using this equipment for 3… I have been using this equipment for 3 weeks straight and been following the instructions. I have good filtrations so for me the product claims of eliminating aquarium smells was what attracted me to purchase the product, so far it’s a big disappointment. My aquarium is not overcrowded, just 4 goldfish in a 55 gallons, feeding 3 times daily. Save your money, product is next to useless.

Shipping was fast Shipping was fast. My tank was only having a slight discoloration to it, when looking long way through the tank you could notice it. The unit was on less than 24 hours and it was gone. Now when looking through the long end of the tank only discoloration is from the glass. Worked way better then expected.

Clarifier Excellent communication. Great shipping. Looks like a quality product,but only time will tell.
