Had to fish Toby the goby out of the return chamber again. Looking really thin. I’m wondering if his shrimp buddy passed on and he hasn’t been eating. If I see him in the sump again, I’ll pop him in a 10g in the basement to fatten up and recover. Move him back once he’s increased in size a bit Dialed back the return pump to 76% to drop the water level in the DT. It’s now half way up the weir slots. Tuning the BA to compensate was as simple as turning the valve 1/8th turn closed. Took 3 minutes to stabilize.
