It looks great, but now we can debate about your reactor output! I would recommend (unsolicited, sorry!) as slow an output as you can keep steady, like a drip/second, until you get your reactor ph steady at 6.6-6.7. (If you're using ARM) A slower drip of lower ph effluent will actually help keep your tank ph from dropping. It's counterintuitive, but true. You can use a Salfert alkalinty test kit to check your effluent alkalinity; shoot for dkh25 or so. You'll have to wait several days until the media is completely settled to get an accurate effluent alkalinity test result.
