Here is my 50 gallon cube build upgraded with spare equipment I have sitting in the basement. First I went with a Herbie overfow pretty much silent went with schedule 40 1 inch PVC. Then I swap out the return pump with a Reef Octopus VarioS 2, for flow a maxspect gyre 230 mounted vertically on the back wall and the light will be a maxspect razor 16000k 120w. Running the whole tank is an old reef keeper. Didn't want all the equipment under the stand so made an equipment stand out of a old cabinet from Ikea. And thats pretty much it
