Review on 🐠 COMOK 4-Way Aquarium Air Control Valve with Flow Switch by Olga Allen

As with most mass produced products, the black air control valves will eventually need to be replaced. two, one each for my 36 gallon nose and a 38 gallon nose to connect the stock air hose with some decorations attached to the air stones and foam filters. The problem, however, is attaching the item to the tanks, which requires some ingenuity on your part to make it work. that at this crossroads I am still trying to find a solution. Anyway, the device does a decent job, but until COMOK adds a "ATTACHMENT DEVICE" to this product that allows it to be attached to a tank and fitted with a protective cover; I can only "reluctantly" give it 3 STARS.
