I use AB+ too and my corals look fabulous. I had a ton of problems connecting with my ReefWave 25 on the onset, now, I have no issues. I think the initial setup is a bit cumbersome. The people at REDSEA are very helpful, though. Give them a call to see if they will help you. You are right that it feels like it shouldn’t be as tough as it is. It is very frustrating and scary when you have so much invested. If you look at it from their perspective at how difficult it must be to build a product that has to integrate with so many different systems and configurations, maybe you can see their side of it? It will all work out in the end. Take care. JL
