Dream set up for a planted tank with sump?

[cornishrooster]

Hey yall I've been doing some research for a new 125 build and wanted to get some opinions on some good gear for growing plants in my new tank. I've had live plants for some time but never anything to the level that I'm imagining for the build, in fact I've never used co2 from a canister. Always managed the plants with liquid products that seem to work. I'm thinking I'll mod a cerges reactor into the return for the pump but I would definitely like to hear some thoughts about this. Anyhow I've set aside a ridiculous budget for this project so tell me what you would get if money were no object and keep in mind I would like this to be mostly an automated system. Thanks!
