Suggestions for a controller and doser

Have about 800 gallons tied together, mostly tangs a few other fish and a few corals, what would be a good controller and doser suggestion, Jim

Cant go wrong with the apex. What are you looking to dose? If just 2 part apex makes the DOS system. While it had some troubles early on I believe they have it dialed in pretty good.

I've got the APEX and DOS. Using apex to control a 50g reef tank and a 175g planted tank. Use the DOS for plant fertilizers. It was extremely easy to set up.
