I have done this, but, per advise of the septic folks I dump more often and less qty at a time. What you don't want to do is overfill the first stage and cause solids to flow into the second stage. It''s not necessarily how fast but how much over a relatively short period of time. A home toilet only flushes about a gallon and a half. A shower maybe 10 -5 gallons even a laundry is not all that much quantity of water.
If you have a 30 gallon tank, flush it when it gets a 1/4 to 1/5 full and just more often. I would also not pump your grey tank out at the same time. You have to allow time for the solids to participate out in stage one, before the water flows to stage 2 and beyond. You don't want to get solids in your drainage field, big $ at that point.
