Hi All from New Zealand, I have just finished building a FRAG TANK / BACK-UP Reef Tank for my 600 gallon that I will be building in the next 12 months, but first I have to get all my fish into this back-up tank. The main tank is approx 160gal with 2x 30gal sumps joined by a one bulkhead, so the total system water volume is approx 215gal. I am only using one 25mm bulkhead to connect the two sumps through a 35mm drilled holes. I plan on using a powerhead to help the water flow through the bulkhead to the other sump. Anyone done this before or have any advice before I go ahead and give you all my ideas?
