Very nice! Thank you for sharing.

Nice work, I added an effuent chamber from an old Red Sea Merlin fluidized bed but it's a real PITA to refill, your recirc mod looks way better. Are you using ARM for your CA media?

with the recent sale at HR, i bought and switched to the coarse ARM reactor media. The sizes of this media makes the flow through the reactor very easily. I had used the Caribsea crushed coral substate with good results but the ARM media is a lot bigger than the crushed coral.

I was thinking about trying the coarser Arm as well. Do you think it dissolves slower than regular ARM?
I've got this K2R cranked up and it goes through media pretty quick.
I guess I could always mix them and see.

its too early to say right now. i put three containers of the coarser ARM media into my reactor and i'm still trying to fine tune the output of alk and ca to my tanks' demands
