Did you have any trouble getting the M1 back together?Minor catastrophe this week. My return pump (vectra M1) got clogged with chaeto so I had to pull it and clean it out. Probably due for that anyway since it's been running for ~11months. I ended up having to slow down the pump by 2 steps because it was pushing way more water after the cleaning.
Everything went smootly until the next morning I noticed a ticking/clicking sound. Figured it had sucked something in again. Pulled the pump apart and sure enough a hermit crab had found its way into the pump. And then the problems started... The stand lights cut off. Huh, weird. Then the skimmer turns on. I grab and flashlight and start pulling power cords out of the strip when I hear a sizzle and see water dripping!!! Apparently messing with the return pump caused the return line union to loosen up just a bit and it started leaking right into the power strip. Seconds later the GFCI trips and everything on the tank goes out.
Fortunately the damage was limited to the power strip. After several minutes of cursing and drying things off everything was back up and running.
In the good news column, I got Triton results back and this might be my best results ever. Everything is in the green except lithium, which is caused by my use of Instant Ocean/Reef crystals (sidebar, not a fan of RC, but Amazon has been out of IO for awhile)

My M2 is a pain to align just right. I find that if I don't get it exactly, the impeller won't turn at all. It took me 3 tries the first time before I figured out what was wrong. The cover has a fraction of a mm of wiggle room, and needs to be right in the middle of that slack, then tighten all 4 screws a bit at a time, testing the spin at each stop.
Maybe it is just mine, or just the M2s...
