OK, this one should earn my idiot points for the year...
I've got an AC Jr on my 18 month old, 29g nano. A while ago I went to perform a 6-9 month cleaning on my return pump, only to find it solidly embedded in a 1/2 inch of calcium rock. Not budging. My peristaltic pumps dose 2-part into my return, but the flow's pretty good. How did this happen?I just realized how...
I use the OSC function to dose calcium into the return 1 out of every 50 minutes (roughly). And I use the "Feed" mode to turn off my return for 15 minutes while feeding. But I NEGLECTED to turn my OSC function on the calcium pump off. So roughly one third of the time that I shut my return off to feed, the return section of my sump had calcium pumped into it.
Sharing so other AC users won't make the same mistake. If you are pumping 2 part into your sump, and are using the Feed function to turn off your return pump, but SURE to turn off the calcium dosing too.
The rock that my return is stuck to is evidence of what may happen if you don't.
