Well I'm finally at the end of upgrading to a 120gal tank in the dining room with a 30 gal pre-sump a 75 gal refugium and a 30 gal post sump/fuge in the basement. It took awhile to plan the layout then the actual work of drilling tanks, plumbing, 2 electrical panels with 18 GFCI outlets to each assembly, modified plumbing and automated water change system, custom made acrylic brackets for refugium lighting, ATO float valves, ORP Probe and PH probes. A Modified ATO system, custom effluent container, custom made lighting 2, 250W DE MH w/4 T5 actinic bulbs and 4 moon lights with a quiet air cooling. All that's left is to hook up the laptop to the Aqua Controller, DC8's and X10 then automate the calc, alk and mag with peristaltic pumps to an amount of flow dosing a calculated flow. Then I break down another 90 gal tank so I'll have one tank to deal with. It's a ton of work but it be worth it when it's all done.
