Seems like the top has good movement. Do you have a lot in there? Doesn't seem like bottom is moving.

It is a BRS jumbo reactor. 6 cups of regular GFO. I can adjust the flow by using the gate valve on my manifold. But if I adjust it up enough to tumble the bottom, Im afraid the top would beat itself up and disintegrate.

I havent run GFO in close to a year, and that was in a Nexreef MR1. First time using the BRS jumbo.

Seems like you might be blowing it out the top with that much gfo in thecrwactor. I would not fill it past 2/3 and make sure the effluent goes into a felt filter sock so you don't blow the dust everywhere.

6 cups seems like alot to me,but Im not sure. BRS has a calculator on their site you can use.

Also it seems a bit strong to me up top. You only want it to lightly dance on the top from my experience.

According to BRS website it 'Holds 6 cups of carbon or GFO (Designed to use only one media)". I actually have 2 of these reactors. 1 is currently not in use. I may turn off the first and divide the GFO between the 2 of them then turn them back on.

I am currently running it into a filter sock to catch any fine particles that may blow out.

Im not speaking of how much the reactor can hold. I'm speaking of how much GFO you need for the volume of water you have in your system.

Here you go!

Approx 6 cups granular, 3.5 cups high capacity.

Be careful. You may want to cut the amount in half (or more) and let the PO4 drop slowly. I did a "recommended" amount after not running it for a couple of months and really , really ticked off the tank, especially the sps. No polyp extension for weeks, and ended up losing a few. Your tank is looking awesome, I'd hate for you to suffer a setback.

I think the flow is a bit high in there TBH. You want it slowly tumbling on top not bouncing and jumping.
