Also, skimmer intake is hooked up to 1” flexible line running outside. Eliminated CO2 scrubbing and also liking it.pH has stayed nicely at 8.4-8.5, parameters all basically where I want using @Randy Holmes-Farley high pH 2 part mixed to double strength w/ doser, Reef Octopus Regal Ext-250 and Bubble Magus roller filter. Not testing often and loving it.
I think most of my hassles over the past 16 years have been due to too much bioload for my previous tank sizes.
