I installed the M-7W in my 200-liter freshwater pond and noticed a significant reduction in algae growth within a week. The water became much clearer and the fish seem more active. The cable is long enough to place it away from the surface, which is helpful for outdoor use.

Works well for my indoor aquarium. The UV light runs quietly and the water clarity has improved noticeably. I didn’t see any issues with the unit after two months of use.

Great value for the price. It’s easy to set up and has been effective in reducing bacterial growth in my pond. The 22cm size fits perfectly in the filter housing without taking up too much space.
