Switched up hardware a bit recently after looking for things I could from Kraken/WaveEngine. Basically all pumps will now be driven by two WaveEngines that are powered from Krakens. So with two 100AH batteries I should be able to run system fairly normally for a while now.
Added two Octo Pulse 4s for flow. They seem nice and quite so far, if not run at 100%. Gyre XF350 on the other hand are quite noisy at anything past about 40%, so will see how they perform, I might swap them for another two Octo Pulse 4s.
For return pumps I switched from Sicce Syncra ADV 5.5 to two VarioS 4. Probably won't need to really control them too much, but again lets me run them off of Kraken's battery at half power.
My LFS Top Shelf Aquatics was able to get me pretty much all the hardware I needed, so that was a sad day for my wallet.
But now I have all the hardware lol. Only things I am missing are one X10 that is on back order and one WaveEngine (got a broken one from BRS, pump port 1 was not powering up), so once that return gets processed will need to order another one, along with couple of bus cables.
However, I am still waiting to hear from Luna Reef about starting my sump build, so the main blocker at the moment before I can proceed further with the build.
Also I was able to setup a more automated RODI and ATO refill. So now RODI barrel refills once level drops low enough.
I can technically do the same for ATO barrel, but left that as a button press in Hydros app for now, as running that big pump controlled by two optical water switches seems a bit scary lol. RODI filtering has a fail safe of float valve that this does not with 1/4" pipe at the end.
And finally, just got a new 3D printer to my collection that hopefully should yield better results than my old FDM from Creality. As well as less toxic ones that my resin printer can do lol. As far as I can tell PETG should be a good fit here for near water environments, I do not plan however to put any of these into water as I do not trust quality of these plastics enough
