I guess that makes sense as the best option. All the fish are doing fine, & because the fish are what's most important in this tank, I leaning toward just leaving well enough alone.

That's basically what I am doing

The returns point down now.

The ARO valve does leave a bit to be desired. Would you recommend the M3 valve?

My previous post was incorrect. It's a Rio 1100. Anything bigger won't easily fit where I want it.

Yes, in the sump with the outflow directed to the main return pump.

That's probably close to where I am. It's difficult for me to accurately count bubbles at this rate.
After reading the responses I have received so far, I went back & tested everything again. It turns out my pH Pen was substantially in need of calibration. I reset it & got readings more in line with what I am targeting. This morning, pH is 6.7, KH is at 4. I am currently slowing the CO2 at night to about 2 bubbles/sec. One half turn on the regulator drops the pressure just
enough to reduce the flow without trying to adjust that finicky ARO valve.
Thanks for your reply
