With the larger fully stocked tanks like yall have you don't have a problem with not being able to keep up with the demands? Thats the reason I was going to try the reactor- most people on r2r and rc said they just could no longer keep the levels up with 2 part. I guess if nothing else you could just run two dosing pumps if it ever got to that point. My plan was to dose until I could no longer do so but if yall can pull it off with just dosing pumps, hopefully I could as well. I guess time will tell.
