as much as i enjoyed my upflow Its time to move back to a water flall scrubber.
I went ahead a bought a little Ehiem pump for $30 should last years. has adjustable flow rates and I might add a gate valve to dial it in more if need be.

Remember, that flow rate is after head loss. So if you bought the Eheim Compact+ 1000, that's not going to cut it as the head loss curve on that pump is pretty steep. At a 12" vertical rise plus other plumbing losses, you will start out at <200 GPH and that will drop fast once you get an resistance. I ran one on an L2 for about 3 months and the flow dropped to below 100 GPH.
