    Nothing lately man. Been super busy with work 6 days a week. Hoping I am off this weekend too go get some plywood and start cutting it up to get the stand started. I did get a Reef Octopus 150, so that's out the way .
    Also been looking at the Ocean Box designs for a 20 gallon long sump. Just not sure yet!!

    So I have been thinking about the plumbing. It is 1 1\2" coming out of the overflow. Can I keep it at that size all the way down to the sump or is there a reason some people reduce down to smaller pvc?

    You can reduce it. You would need to be rolling some water through there to keep that size pipe supplied with water. Would be hard to silence. You can reduce right after the 90 going down to the sump.

    Whats your return gph? Take into consideration schd 40 1.5” pvc can flow up to 2100 gph. 1” is around 960 gph. I dont see a 40B getting close to either one of those so 1” should suffice.

    Those numbers are taken with gravity or the suction side of a pump. With pressure you can use smaller pipe and achive those same numbers. Thats why you can use 3/4” pvc on the return line. With a small amount of pressure(return pump) 3/4” will flow up to 1410 gph.

    I would think so. Can you get your hands on a bulkhead reducer?
