View Full Version : Brs dual reactor, mag pump 9.5, no tumbling

I bought a dual reactor and just got it set up tonight, I have it t'd off of my mag 9.5 return pump with 3/4" hard pvc. I added the recommended amount of gfo and carbon to my reactors, and an unable to get the gfo to move. Only a few particles on the top of the canister move.

My question is, should I remove some of the gfo and/or carbon to better the flow, or do I need to buy a dedicated pump for the reactor? I assumed that a mag 9.5 would be able to handle both the return and reactor. If I buy a dedicated pump, what gph should I get to assure enough flow?

Recommended based on brs calculator is 1.5 cups gfo, 1.25 cups carbon (cheap carbon and gfo, 100gal total volume)

I got it to tumble this morning, but it's only moving on one side of the container, if I turn up the flow, everything goes crazy and shoots to the top of the canister

Only the top should tumble. I use just about the same amount of GFO your using, just the very top "boils".

Hey there,

There is a fine tuning involved to get that right amount of tumble on the top of the GFO. It sounds like you found the both the low end and the high end, from no tumble to max tumble. The trick is to make very small adjustments until you are somewhere in between those extremes. :)

If you notice one side of the GFO tumbling but not the other, that is an indication that your reactor itself is leaning one way or the other. To get an even rolling GFO, you may want to change your reactor mounting until it is balanced. ;)

Please let me know if I can help!
