Im looking to upgrade my display tank. I want to add a controller to monitor PH, salinity and tempature. Perhaps add an ATO down the road. I don't think I need to monitor ORP. I was looking at an apex controller but wasn't sure what would be the most appropriate unit. As being able to balance affordability and function are important to me. Obviously being able to web control is a huge plus. However I've read mixed reviews about Apex; on one hand I hear apex is the best but on the other I read they have a horrible warranty and customer service. What are general thoughts and experiences?
