Fluval In-Line UVC Clarifier: Keep Your Aquarium Filter Clean & Clear

JasonhawuJasonhawu: So much better than I expected. I set up a new tank and had a big algae bloom. Water was so green after many water changes.

I was debating between this and the green killing machine and choose this.

As soon as I installed it, I did a 50% water change and left it running 24hrs and was clear within 4 days.

My water is clearer than anything I’ve seen. I’ve reduced it to 12 hrs a day now to see if it can stilll hold.

Luke Loughran: Went from being merky green water to crystal clear in about 2 days.. Have now dropped the setting to 4 hours a day. Hopefully this will maintain it. Very happy 😊

NorthernSage: So I was a little skeptical on this but took the plunge it's on a fluvial 207 for my tank with two big Ranchu in it. They are poop machines and even if your water is on point closiy is an issue. This removed it in no time it's like my fish are floating. It's only a little of an edge but that's all you need. Basically a posh water polish but nothing but the best for my Ranchu.

Shawn: I had a nasty bloom in my 75gal , it was crystal clear within a week. It's nice to know it's also working on other bad things in the water column like bacteria and parasites. The timer is super nice, simple. For me it's a small price to pay to have less to worry about in my tank.

justinjustin: I have a 32yo turtle in a 40gallon tank. After a 50% water change the water became extremely cloudy. I tried everything to clear it up but nothing worked. After about a month of cloudy water I decided to give this product a try and boy am I glad I did because it worked! After 48 hours of this running 8hours a day (on a timer) it made the water crystal clear! I have no complaints. It was easy to install and runs silent. if you were on the fence about this, just get it trust me.

Britt: I didn't like having to screw it into the side of my lovely oak stand base but I was so tired of my tank looking like it had been filled with mountain dew! I especially love the run timer because it leaves plenty of things in the water for all my mussels to feed off. I can finally see my fish after 4 monthes of water changes, shocks, and chem balances. Sometimes you just need a little bit of extra.

Alban Zogaj: Took about a week to notice the change in the water, but it’s crystal clear from every angle. The only thing I don’t like which isn’t a big deal isn’t besides the lights on the control switch you can’t tell if the UV is actually working. Supposedly on the switch it will let you know when it isn’t. Either way I have it set to 4 hours a day over night and I definitely can tell there is no cloudiness to the water or coloration. Highly recommend if you want to keep your water at its best.

JOHNNATAN ZAVALA MENDEZ: Muy buen aditamento para los filtros fluval, cristaliza el agua casi desde el primer dia, sin duda es algo que no puede faltar en el equipo para acuarios

Francisco Erick Galicia Lozano: Muy buena opción para mantener la pecera libre de algas que enturbian el agua, sobre todo si se tiene una lámpara RGB para iluminar las peceras, que también son buenas pero por lo mismo favorecen la proliferación de estas algas porque equivale a recibir luz solar.
