Review on OCTO OCT-MF300B 2.5 Inch Media Reactor - Superior Water Filtration Solution by Christie Cox

Worked great for the first two days. On the third day I noticed a rattling noise coming from the pump. I turned off the pump, plugged it back in, the noise went away. I woke up on the 4th day to the pump pounding again. This time I couldn't turn off the pump completely. I removed the impeller to make sure nothing was binding or making noise. It was clean. I noticed that when I dialed the flow down through the activated control valve, the chatter started. I'm using a reactor to run the GFO, so the flow needs to be low to keep the GFO from grinding. Long story short, as much as I'd like it to, it doesn't work, so going back. Will try another brand, you might get what you pay for so I'll try something that costs a little more.
