Hi. Thanks for the welcome. My name is Doug. I'm located in SW michigan. I have been a professional tattoo artist since the mid-1990s. I currently have a 75 gallon high tech tank. Running a diy co2 regulator with a matheson fm-1000 flow meter and nilocg reactor. For lighting it has a chihiros wrgbii pro. I just switched to it from a 4 bulb t5 fixture. I also have a 40 gallon breeder that I am setting up now. It has an onf flat one+ and another diy co2 system with a matheson fm-1000 flowmeter with high accuracy needle valve. Then I also have a 20 gallon long that I use as a plant holding tank that has a cheap f-zone pro co2 system with in tank diffuser and a twinstar sa 600 light.
