I've been battling algea since i set up my aquaium. I could do complete water change and 2 days later water would cloud up and start truning green. This thing cleared my tank up in about a week. Worth every penny if you have algae problems.

Fluval Spray Bar is awesome and excellent products and suits for 306/307 & 406/407 fluval canister filters. Now my 46 bow front tank was looks so cool and more beautiful and also my fishes got equal oxygen water flow! EASY TO INSTALL. but it's expensive! I strongly recommended this product.

Easy to install to give your aquarium a even spread out outflow from your Canister Filter. I connected the spray bars to my Fluval 306 filters. My tank is 4 ft across, and I bought 2 spray bar kits, so I had a bar on each of the two 306 filters on my tank. Heavily planted, 6 Discus, Rummynose, Neon, Serpae, Ram, Cory's, Black Skirts and Black Ghostknife. Spray Bar helps tame outrageous flow from the 306, and my Guppies are no longer blown out.

very easy to install, appears to be doing the job.Shortcomings ,NO INDICATION THAT IT IS WORKING IF THE TIMER IS NOT INSTALLED.WHEN BOLB STOPS WORKING CAN NOT BE REPLACE ,HAVE TO BUY A NEW UNIT
This purchase for my 1st UVC unit from Fluval, was a game changer. I have a 60G freshwater Amazon planted tank with 5 Discus. I run a pair of Fluval 306 filter pumps and was just having a difficult time of getting the water to clear. I use a spray bar on each output, and the amount of particulates this would stir up was just not acceptable. I ordered 1 unit to see if it was going to make a noticeable difference. Well, it did, but now I needed another because I have two filters pumping on this tank. I have both set up, after about an hour the tank was clear, without the nasty bacteria floating about. For about half the price they wanted at PetSmart, I got mine on eBay and it was worth the effort.
I this light 4 months ago I it is very good the only thing I don’t like is I can’t clean it. Every time I clean my filter and houses and put everything together when I start everything I can see all the dirty stuff come from the light. I want to call fluval and tell them the next uvc light they make have to be easy to clean
It looks good and well made and the online timer is a nice touch but the unit is not serviceable for cleaning so for how long it will actually work is a little questionable.
Its hard to know if this is working. I dont have any green water, but i use this preventatively. So it might work great, it might not. It is easy to install with the 207 canister filter.
Needed to replace the spray bar on my FILSTAR XL, but that product (nor replacement parts) are no longer made. Saw this listing and very helpful retailer provided pics/dimensions. FITS 100% PERFECTLY as a replacement! Looks like exact mold was used to create product; I wonder if FILSTAR was bought by FLUVAL b/c pieces/sizes are exactly the same.
Had green water that just wouldn't go away. Bought this, hooked it up to a Fluval 307 canister filter, plugged it in, and let it run 24 hours a day. Every day there was a noticeable difference and the water slowly started to clear. Within a week the water was crystal clear. It's set to run for four hours a day now and the green water hasn't come back.
