Ya, it hasn't been the best experience we've had adding fish and its especially hard since we've waited so long to add these guys.I’m really sorry to hear about the electrical problems and your losses. Its always upsetting when things that are out of your control cause these kinds of issues.
As far as the pump and 3d printed part is concerned they both continue to work like champs. Highly recommend both the Reef Octopus VarioS2 for the pump and eelrivercorals to make the parts you’ll need.
I'm glad to hear the pump and part are working out for you I'll be tracking both down this week.
