## Description

Barbed Aquatic Ball Valves for regulating water flow through standard hose used for devices such as canister filters, pump return lines, protein skimmers, calcium reactors, etc.

Review: Works Well - I bought this ball valve to use inline in some tubing going from my canister filter to a chiller on my 20 long axolotl tank. It works great. It allows me to cut off the chiller when I want to...for whatever reasons I may want to...and it doesn't leak or let any water through. It fits the tubing perfectly and seems well made. If you need a cutoff valve for your line, this is a great choice.
Review: If you have Dyslexia like me, please read. - This product is great. I own about ten. I have never used clamps and have never leaked. They grip .5 inchinch inner dismater rubber hose so well that once it is on you have to cut them off. Problems I want to have. However, first time buying, I thought I was buying "Two" for the price of one because of the company name. Laugh. Its sad to be me every day. :). But to be clear you are getting "one" valve from a company called "Two little fishes" not "two" from a comapny called "little fishes". I am wrighting this because as dumb as I am, I hope and pray there is at least one person who is dumber.

### ⭐⭐⭐⭐ Great product! Just a few more things you will need.
*by A***R on February 26, 2017*

Really great product and easy assembly with clear instructions. There are a few things that you will need though in order to make it run 1) Some sort of powerhead air pump depending on the size of your tank 2) a flow valve regulator to adjust the intake of water for getting the flow rate just right 3) 1/2 inch plastic tubing. Which I got from Lowe's for like .19 cents a foot. You may have to heat the tubing up with hot water in order to make it go on certain parts 4) your desired filter media. I did rox carbon and it cleared up my cloudy water that night I hope this helps in case you are confused on what else you need to buy.
