Review on 🔧 Enhanced A1175 Fluval Plastic Air Control Valve for Improved Performance by Melanie Harris

I bought it because of the large handle to make it easier to dial a drip line drip account. I thought it was a rotary adjustment and didn't realize it was a 90 degree ball valve. It works great as travel or course use, but it's hard to move and forget a dropper kit. Ziss produces the same price, which I really liked. Seeing Amazon's choice playing a major role in my direction I thought it would be like this but maybe not as difficult to spin as Ziss but this one has a paddle grip and is tough to move around etc. I have a big pump on two tanks and some separate sponge filters and stones and this thing will not adjust or adjust at all eventually you will try to go back to the starting point.
