Strange, KH at both sump n tank should b same unless u just dose sodium bicarbonate in the sump which need time to achieve uniform mix.

Ya... I think I tested just after a dosage was applied by the dosing pump...

Hmmm... That's what Henry says too... How to improve sump circulation ??

Thats odd. I guess u can increase ur return pump flow. Else just add a powerhead for added flow.

Maybe my DSB refugium is slowing things down ?
