Hello. I was fortunate enough to come across 2 full DAS commercial rack setups. Basically they're 3 glass 75 gallon tanks stacked on top of each other. They're split up into 1, 2 or 3 individual tanks per row. Each one has an overflow box made for a big sponge and powerhead. As it stands I have 14 boxes and am looking for energy efficient powerheads since I'll be running so many. I'd also like to use larger ones for the full 75s and smaller ones for the tanks split in 3. Does anyone have any suggestions based on quality/price and energy consumption? Thanks!
