46 gallon reef.. current stock plus probably a few (4) chromis and a dwarf angel. The 20 gallon will be its sump, cause the stand restricts the size of the sump to about that.
I will first buy a water filter.. most likely when I get my tax return, before the 46 is even broken down. Then when its in its new place powerheads, sand and rocks go in for a cycle. then another 96 watt fixture for a total of 192 for just over 4wpg... I will add the chromis first to make sure it's safe for my other fish. Once the other fish go in to the main tank or 10 gallon quarantine the sump will be built with a HOB overflow.
should cost about 650 to do... hopefully...but will be more like 700.
