If you start the filter running with the in/out tubes in a pitcher,
then the DE (diatomaceous earth, or diatoms) can't get into your tank. 
Don't take the pitcher away until the water in the pitcher is clear and
no mor DE so then be passing through the filter -- then none should get
into your tank.

I couldn't agree more that quick disconnects, a recharge/recirculate
valve should be standard items included with every Vortex.

On the D1, the motor is a little over 100 watts (a Fasco).  I imagine
the XL is evenhigher wattage.  Quite a jumo up from, for example the
Eheim 1250, which consumes only 28 watts, but doesn't produce nearly
the pressure the Vortex requires.  I would expect a motor in this power
range to be louder.  It certainly makes it less important how loud the
cooling fans are on the lights.  ;-)

You said it.  DE for filtering, rather than a soil additive or
pesticide, is rinse/washed and calcined  -- wet it and bake it. 
Whether it's used for pools or comes from Vortex, it's mostly mined in
California and it's all the same.  Moral -- buy the stuff from Pool
Supply house and save $s.
