I am closing my pool soon but the water is kinda green and I am out of chlorine. Is it ok to just drain it and close it. It is a 30,000 gallon inground.

You will want to know the water table in your area so you will know if your pool will come out of the ground due to hydrostatic pressure. That would ruin your weekend.

Is there any particular reason you don't want to winterize it (monthly shock + algicide)? That much water wouldn't be cheap.

There are a couple of reasons not to drain and leave your pool empty. the first is the popping out of the ground problem. Even a good rain that temporarilly raises the water outside of your pool can raise it like an empty ship right out of the ground.

Here's another. If your pool surface is ridgid, i.e. concrete, plaster, marcite, pebble tec, ... any hard surface, it is prone to expansion and contraction with changes in temperature. That causes the surface to expand (Pushing ridgid surfaces together, and contract, pulling them apart, both of which will reduce your pool to rubble over time. In my area, Phoenix Arizona, I reccomend in ground pools remain drained for the shortest time possible, and starting refilling the water within 24 hours of the drain time.
