Fluval UVC Clarifier for Aquariums, UVC Clarifier with CCFL Lamp Technology

A Fluval product user for some years, the inline UV filter from Fluval once again, didn't disappoint.Simple to install and connect with near silent operation, it's suitable for even the most inexperienced aquarist. The cool operation is great as this avoids any heat transfer to the aquarium parameters, unlike most internal UV filters. The timer feature is also welcomed, meaning there isn't a constant drain on electricty. Very efficient and effective with crystal clear water, and a noticable absence of any problem algae across the entire aquarium.

Only been running a week, crystal clear water and visible reduction in particles and algae. Easy to install.

Got this to put on my 307 canister.Was getting couldy water as i seem to overfeed. Cleared up in about a day.People say they take it down to 12 hours when sorted bit keeping mine on 24/7.Very happy with it and easy to fit. Higbly recommend if you like clear water.

This works fine, be better if the supplied water pipe was longer.

This really seems to have 'brightened' my tank, the algae is clearing up (had a problem with green algae) the fish even seem 'happier' less hiding, more swimming. Planted tank has been set up for 3 years.

Installation was very simple and straight forward, regardless of other reviews that almost got me not to purchase this. The hose provided was excellent length. No need to replace any hose others have mentioned on here. Took less than 10 mins to install. Just look at the illustrated picture and do exactly that. duh...!!

I thought it would be good to have a clarifier to keep my water clear but I have the fluval 407 in my cabinet under the tank. This fitted to the flow output tube and then another tube fitted it to the tank output tube. The connectors worked well but it is an absolute nightmare to fix to the wall or cabinet because the tubing just won’t bend and flex enough to let it be screwed down. I did half manage only to find it was almost impossible then to get the filter tubes off the canister and back on. In the end I let it dangle precariously, leaving me worried about splitting pipes until I bought another better one that impairs bacteria and viruses and parasites too. This one just stops green water. Also the flow through needs to be slow on this one to even do that. I love fluval canisters and their aquariums and have both. But this I would definitely give a miss, not least because it doesn’t actually sterilise, only clarifies and because there is no way of actually seeing that it is working as it’s completely sealed. Also because they don’t supply the extra tubing needed to fit this properly to your Fluval canister. I bought a Tmc vecton v2 steriliser instead and am thrilled with it, it does it all.

Now I do understand this is a band aid for a bigger problem if you are having issues with cloudy water or algae but for the sake of having clear water and not messing around with chemicals or waiting and waiting and then for it to come back later and haunt you if you either add too much food or change too much water or this or thatWe know axolotls are picky to there surroundings and parameters. This just helps to keep it clear from bacteria that should not be there or that could harm the little guys
