JBJ NanoZapp Inline UV Sterilizer 3W Replacement UV Bulb
So Far So Great
I ordered this product for my 28 gallon nanocube freshwater set up. I was about a month or so into the nitrogen cycle and had a green water algae bloom. I tried a liquid algae product but online research said that it wouldn't really work. I researched the nanozap and it was priced right here on Fosters and Smith so I ordered it. Installation was fairly simple. I had to cut the tubing a little bit shorter than the instructions say but it is securely in place between the pump and the jet tubing so that the sterilizer would sit perfectly straight in the pump housing. When I cut the tubing to the length in the instructions it was installed on a slight angle. I am not sure of the build quality as it was installed a couple of weeks ago. The housing middle piece screws together securely where the top piece and bottom piece kind of just fit into each other and come apart fairly easily. Maybe it is designed that way for cleaning, water flow etc... Some reviews said it might be a good idea to use clamps to hold it in place. I don't see how that would be necessary if installed in a nanocube because once installed it is securely in place and should not be able to come apart or move without a lot of physical force. That may be a good idea in other tanks but you shouldn't have to use clamps in the 28 gallon nanocube. Within 24 hours of installation the water had cleared up quite a bit and by the end of the second day it was very clear. I will see how it holds up over time and change the bulb at the recommended interval but so far I could not be more pleased with the performance of the product and would HIGHLY recommend it. Dr. Fosters and Smith had the best price I could find so you may as well order here if you like the reviews.

Needs some design changes
The concept for filling the need for uv for nano tanks is great. I had to do some tweeking on my on though. The washer arrangement inside from the factory was misaligned. It let water inside the quartz sleeve. I luckily caught it by observing the light kept on getting dimmer. Had to make sure I tightened the outside sleeve to the point of almost breaking.
I think I got it. It's been a couple of weeks. But I still monitor it. It's the second time it happened. Water ruined my first one. They need to make the bulb fit more securely and add barbs on the input and output openings. If they fixed those items would be great for all nanos

Must Be Submerged
I attempted to plumb this "inline" with my chiller return. It leaks from many areas. The product does function as advertised if plumbed within the JBJ Nanocube filter return line, which is submerged. This was not the ideal setup that I was looking to use.
If you need to have this on a non-submerged return line, this is not the right product. You will need to spend quite a bit more for a Biocube UV sterilizer that advertises true inline capability.
In defense of this product, neither in advertisement or in the manual does it ever say that it can be plumbed externally inline.

I purchased this item several weeks ago, after installing it, the unit leaked from the threads that connects both pieces together. After putting some plumbers tape around that to correct the problem, the next morning I noticed the light not working. If I unplugged and plugged it back in, the light would stay on for about 30 seconds. I decided I needed to return this unit. No problem, they sent me another one... As soon as I installed the new one the darn thing leak in every conceivable spot on the unit! :(
