Having decided to make a monster and looking at kit I’m starting to struggle. DT turnover - 1800g, say medium run 30x volume - 54k g/hr? what pump can handle that? I was thinking 4 pumps would do me but I can’t seem to find anything suitable. Having 54 Eheim 5000 isn’t practical not to mention the cost. Electing for no power heads in the tank don’t like them there. Preference for inlets is for 15mm bulkheads and i’m scoping 36 in all and 3 X 63mm overflow outlets. Any suggestions folks?
