pump it out
Test for ortho phosphates
The water can be drained outwith a hose.
if you had lots of algae in your water, then shocked it, it might look that way until the filter can remove all of it, or perhaps if you have a diatomaceous earth filter it is malfunctioning. how can i get rid of the snow? Do you mean foam? Ya gotta be more specific. Just what did you put in the pool prior to this event? Is the water cloudy? What?
Install a floating pool skimmer
You should check your chemical balances. If they are not in the ideal range the pool will becom cloudy. I would go to your nearest pool store and ask them for the chemical testing kit which will include instructions as well as the chemicals needed to balance your pools chemical levels.
Make sure your chemicals are balanced and add a clarifier available at your pool supply dealer.
Green pool water is caused by algae growth. When chlorine levels drop below 1-parts-per-million, algae will begin to grow. To get rid of the algae, turn on the pump so chemicals will circulate through the water. Correct the pH level of the water by adding an acid or a base to bring the pH level to a 7 or 8. Clean any debris out of the pool. With a nylon brush scrub the pool, breaking up the algae. Add shock to the pool, and continue running the pump throughout the cleaning process. The water will be cloudy when the shock is first added, but will soon begin to clear. Once the water is clear, vacuum the algae from the pool.
Keep clohrine levels at constant
Put a tarp roughly as big as your pool on it overnight if it is near a garden with good hiding places for small things.
warm water and soap
First of all call a pool company! Are you sure that you don't have a "mustard" algae problem? The heater needs to be looked at and the only way to get rid of rust particles is to vac to waste. You need to address the real problem because you don't want to swim in the pool the way it is. A pool company will test your water at a minimal cost and advise you for free. Rust deposits from your heater are possible if your heat exchanger is old and has glass lined headers. The glass installed by the manufacturer is starting to deteriorate and it is exposing the steel underneath. The rust swells and then breaks off.
Pump it into the sewer or just run it into the garden.
