after seeing some killer systems today, and some deliberation, I think I'm going to go a different route with my return pump, which means I'm selling the ones I just acquired:
Reeflo Hammerhead $240
this pump is in amazing condition, new seals throughout, no rust!, runs smooooth (if it doesn't sell, I will probably stick to my original plan) got it from Reefit when he broke down his tank.
Reeflo Dart $90
new seals, runs great, just got it from ArsonMfg (seeing his tank was worth it by itself!)
BNIB Jebao 4-head dosing pump $90 I love these, but since I just bought a Ca++ reactor, won't be needing it!
