Review on Control Water Flow with Two Little Fishies ATL5445W Ball Valve - 1/2-Inch for Effective Regulation by Veronica Wade

There is one to reduce the filter pump capacity on Fluval Spec for Betta. Seems to be working fine. But wow, this sucker was big. I knew it was going to be a 1/2 inch pipe but I wasn't expecting the valve to be that big. But there's nothing wrong with that. Valve is good and tight. But unless it's in a tight space, it's good to make sure the valve stays in the position you placed it in. Universal version of this valve, for general devices, not suitable for aquariums. The graphics and the logo on it are the same. So if you find this valve cheaper under another brand, go for it. This one is probably not even made from Two Little Fishes, just packaged by them. There is someone selling the same valve at Revain for twice the price plus shipping. So this is the best deal if you have Prime or are buying items worth at least $35.
