Thank you for reminding me I need to do this! Will do it ASAP. I repointed one of the return pump heads up towards the surface and have some nice agitation now. I'm reconsidering adding a skimmer now...was going to wait, but may get one ASAP.Is the ph meter calibrated?
This reading is the only thing that stands out in your readings.
I do see a dust layer on the surface of your water. This means no agitation. Be mindful, if your house is tight and you have high co2 in the house, agitation won't help to raise the ph.
I didn't see a skimmer in your list.
Do you have one?
