I recently started an 18G AIO, after adding my sand and rock I figure the actual water volume is around 14G. If I was to turn both the rear overflow compartments into a refugium, place the skimmer in another compartment, and then the return in the final I think I can set this tank up tk be run on the Triton Method. The two overflow compartments are 0.8G each or 1.6G in total. Could this work?
