Yikes .... my brain is overloaded on all of that. Honestly, I have not dove into the Apex, Hydros level of reefing. I'm at the smart power strip level... I'll do some digging tomorrow and see what is compatible with the AutoAqua AWC that I have. I did not even think about needing a solenoid to connect the RO to the float valve. I love the idea of a safety flood sensor. I just don't know that I am ready for all that specialty stuff yet. Baby steps. You are definitely giving me something to consider though... thank you!
