I have both Vortechs hooked up now. I noticed after the first one was powered up that the skimmer was producing wetter skimmate. When the second one was switched on so much crap was kicked up that the skimmer bucket overflowed for the first time. I installed a bulkhead and elbow on it at the beginning so it overflows into the sump and this was the first time I saw it in action. Simple but effective.
I turned off both closed loops a few days ago. The one on the Dart is not needed as the first Vortech is there and I turned off the big Sequence 1000 that runs through the rock racks to see once and for all if the microbubbles would dissipate. They didn't.
Anyhow, I was able to align the second Vortech as well as the first. The next morning I found the motor section by the side of the tank. The tab that was stuck to the tank and zip-tied to the cable had simply pealed off its glue sticky thing. So this leads me to believe that the propeller section had spun off due to misalignment and without the magnets to hold it in place the motor fell off. I now have two of those tabs stuck above teh motor. Anyhow the soft gasket that goes on the inside of the tank which the propeller section sits on disappeared under reef so I powered teh big Sequence up to flush it out and it did come out. I left the Sequence running now.
One thing I've noticed with both Sequence pumps off is that it's easier to maintain a cooler temperature. I think the two pumps add at least 1.5C to the temp as it's been 34C (95F) all this week and the reef hasn't topped 27C (80.6F). I also lowered the night-time temp to 25.7C (78.2F) as with the halides off and air con on it gets chilly in there at night and the Finnex heaters kick in. So heating up that extra degree takes time so doesn't give the tank so long to heat up after it hits 27C. I've also been running the A/C in my office 24/7 so the QT tank doesn't overheat and I usually leave one of the access doors open. So all these things have helped me battle the heat.
The halides are going off in 45 minutes and the reef is now at 27.5C (81.5F) with the big Sequence running. I really think 27.5C (81.5F) is as hot as a reef should get in order to keep the corals healthy.
I suck at aquascaping! I pulled the left island apart because (a) I wanted to build it a bit higher, (b) in order to place the new corals better and (c) in order to move the LTA over to the far left out of harm's way. Unfortunately I found it had split (yet again) and one half is living under the reef. So it could pop out anwhere at any time and that makes me nervous. It's still towards the left so I left an opening to coax it out that way if it wants to come out.
The new corals are great but I need more to make any kind of impact.
