That's good to hear!

OK - I also understand the closer the pump is to the filter and the
less tubing involved - give you better flow or more oomph.

I'm now looking to buy tubing. Expensive!

I'm either going to get (2)-1800 gph pumps or an 1800/2400 combo.

The 1800 has an output hole of 3/4"
The 2400 has 1"

Should I get 2" tubing for these 2 pumps? Or 1.5" Which would be
better for more flow or doesn't it matter at some diameter point?

IMHO...go as big as you can afford...you can always put a valve in line to
effectively "make the pipe smaller". Small pipe can't be made "bigger".
