Wait, you want to get back on topic? Why? LOL
I'm not quite ready for the rock yet. I built the cabinet (basically a rocketEngineer one, bit lengthened to house the sump) and and the poles for the light(s) , but I'll be switching sumps at the same time from a 20 gallon tank to a 24x24 footprint acrylic.. I have to baffle it yet and do all the stupid math to figure out how high the baffles need to be, which will be complicated by the fuge draining to it in addition to the tank.. and I hate math.
That is why I asked for opinions now, so I could let this whole thing percolate for a while, and research the comments folks give me... I try spend time on decisions, weeks or more... I learn something new everyday, whether I want to or not, and letting these things evolve over some time allows me to focus on an 'area' for research without overwhelming myself with more info than I can handle. And I'm reading your thread and watching football, that actually a little MORE than my tiny little brain can handle!
