Dual intakes ??

[Dennis]

Opinion wanted:

75 gallon tank
Rena Filstar xP2 canister filter

Would the tank filtration benefit with two intakes (by adding a T
connector) ??

Would this cause problems with the canister filter ??

I think that 2 intakes put far one from the other is better that a sole
intake because the refreshment rate is improved.

It would seem to me that the intake with the least resistance would
get most of the flow. The other would languish. I may be wrong...just
sitting here trying to envision it from a hydro-physics-whatsit view.

It would reduce the drag coefficient slightly, giving a net increase in
flow. I don't see it causing any trouble with the canister provided both
were filled with water (getting all the air out of both might be a
challenge). The extra connections (the T) outside the tank are a
weakness (a system is as water-tight as the number of connections). The
flow will initially be equal (assuming they are the same length of hose
from the T and at the same depth in the tank), but this will quickly
change as debris collects at the intake grid. A difference in flow
should have no effect on the system's operation. If the intent is to
better circulate the water, then this works, to a diminishing degree as
they clog. It provides a nice level of redundancy for intake clogging
stopping the filter.

That's how I see it happening.
