18x 36 IG grecian pool, approx 27k gallons

Next, opened pool 2 weeks ago, swampy green, and 3 continuous days of 3 big walmart jugs got things to cloudy. Things were coming along quite nicely until I realized the big brown smudge in the shallow end was SAND!

Found the vertical pipe in the sand filter broken off at the base. Replaced and replaced the sand. Water cleared to a point and I broke out the secret weapon of DE powder this morning. Added about 1/3 cup and pressure went up one pound so things appear to be good.

How long before water clears? I suspect the cloudiness is dead algae and pollen. Pool does hold shock value overnight. Wife is getting impatient.
