Fluval FX UVC Inline Clarifier

After watching a few YouTube reviews I decided to take the plunge and purchase this product. I didn't consider the water in my 360 litre Discus tank to be cloudy or green but I went ahead any way and made the purchase.After just two days I'm really pleased with how crystal clear the water in my aquarium is. My Discus are looking great.Well done Fluval, it's five stars from me.

Too soon to tell if it's having any effect on water quality, if at all.Returned the first one as the indicator light on the end of the unit didn't light up.The second one is the same. Water goes through and there is definitely power to the unit but the light as shown in the instructions does not light up to show the unit is working.Edit 31/12/23After 3 months of use this seems to be doing nothing for my tank. Very disapointing for a Fluval product. Also there doesn't seem to be a replacement lamp available yet so I can't even replace that to see if that fixes the problem.

Added this to the new fx6 and found that when installed on the lid there is slight vibration. Unconvinced that the uv is suitable for such a powerful filter.Set up though was easy and comes with a lot of other bits for different applications

I think it is a good item but I think they could provide the piece of extra pipe required to mount it away from the filter as leaving it laying on top of filter is not great it makes everything look cluttered

After reading the reviews, I thought this was the one that was going to help clear the water in my fish tank. Not long after, the second day I installed it, the algae started to grow, and now my fish tank's glass is green and all the plants are covered by black algae. So answer to your questions, don't waste your money.
