If my calculations are correct, you are adding 2 mg/l of phosphate in each
1/8 tsp KH2PO4 to your 72 gal. tank.  Even assuming the level is zero after
you do the water change, that seems excessive -- about 4 times what Tom Barr
would recommend.  If you would like to check my arithmetic, please contact
me off-list.
