Review: Amazing results in less than a week - My son asked me to order the Coralife UV sterilizer for his 180 gallon freshwater tank after he began having a problem with the algae. The water was so green that you could barely see the fish in the aquarium. Our problem is that the aquarium is in an area where it gets a lot of sunlight. Setup: this UV sterilizer is meant to be installed "in-line" with your filtering system. Before you do anything, make sure that you have a good plan as to how you're going to connect this in-line in your system. and the right parts to install this. You'll need whatever size clear tubing you're using as well as metal clamps. You may need to purchase some 45 or 90 degree elbows to make the turns needed to set this up in-line. I purchased the metal clamps from Home Depot for somewhere around $2 each. I also purchased the elbows from Home Depot. It's not obvious at first, but one side of the UV sterilizer is the intake and the other is for the output (look closely at the intake/outputs and you'll see arrows pointing to the direction the water should flow in. You'll need to secure the UV sterilizer somewhere on the aquarium stand. We used one of the brackets to secure it to the UV sterilizer to the inside of the cabinet. Function: once you turn this on, check to make sure there are no leaks. After one to two days, we started to notice that the water was not as green and cloudy as before. After 4-5 days, the water was very clear. It's now been 6 days and the water is almost crystal clear. I would definitely recommend this if you have a problem with cloudy water from algae.

### ⭐ They look good but definitely some quality problems.
*by N***N on June 30, 2020*

I ordered two of these, and have had to do three warranty returns because of leaking through the top housing. If I could give these zero stars, I would. These are hands down the most expensive pieces of junk I've purchased for my tank which has been running now for over 10 years. The specs are awesome, they do work great at least for a while, but be warned... just like so many other reviewers... they have leakage problems. They leak right through the top housing... some type of molding/manufacturing problem. I'm now up to four leaking units. They all leak internally into the electrical cavity where they short out and then leak externally. I've removed them from service and would never never put them back... time to fill the trash bin. Also the mounting brackets are totally inadequate. If you mount them vertically, they will break - be warned they you will want to secure them with something other than just the supplied brackets
