Review: I have a 100 gallon marine aquarium and I want the best environment for the fish and invertibrates. This filter mounts to the wall in our wash room so it takes up virtually no space. The system is very easy to install and I simply use a valve off of our water faucet to activate it. The results have been great. It even has bypass features for when you change the charcoal to let it pass thru. There are no leaks (very important) and its the best system I have used. Very good quality and I was very pleased with the value. If you have a need for an RODI system, this is the one I recommend.
Review: This item so far did a great job for my aquarium. Definitely a good buy.
