Actually my carbon barely tumbles with the 1200. Maybe I am using the wrong carbon.

Why do you need your carbon tumbles?

Not sure.... I am new to reactors myself... a couple months. I just know alot of media is supposed to tumble in them... but my carbon (Kent) barely moves.

The way i understand it that Carbon tends to be more effective if the water is slowly flowing through it and if too much tumbling action can cause carbon to actually abrade itself into smaller pieces, meaning anything it absorbs can be released back into the tank.

Interesting. I have not heard this before. Maybe its good my carbon does not tumble then.

You might want to look at running two pumps...I tried to run pellets and carbon with a single MJ1200 and I wasn't happy. Now I run a MJ1200 on my pellet reactor, and a MJ600 on my carbon reactor and I'm happy. I've also noticed that if you're not careful, and push the rubber 90 elbows on the TLF reactors all the way down you end up cutting off more flow to the reactor, as the hose barb on the reactor almost butts up to the top of the elbow.

A half full TLF reactor with pellets BARELY tumbles correctly with a wide open MJ 1200. A 600 would work for a GAC only reactor.
