Anyone else get their WP-40?

Wonder if any of you monitoring ORP would find similar effects. The only change done when the massive ORP drop happened was swapping Koralia Mag 7s out and the wp40s in. ORP red, pH blue.

WOW!! I se your graph there and I have NO IDEA what it means... Se I learn something new everyday... I was going to ask What is ORP? & why?? But I googled it and found this artical to help me understand it.

Now is your drop on that chart good or bad?? Sorry to seem dumb on this subject...

In general ORP dropping could mean something died in your tank. It usually drops as a result of a spike in organic decomposition, so its usually bad. In this case, I think the wave motion of these pumps pulled a bunch of organics back up into the water causing the ORP drop. This would be a good thing as the organics get skimmed/filtered out vs. decomposing in the tank. Also this ability to graph aspect of the tank is one of my main attractions to a controller like Apex. Now if they'd just ad some good options for programming/controlling these Jebao pumps
