If it's too high, your water might get cloudy, or you might get scale at the pool's water line or inside the pool heater. If it's too low, it can cause the surface of a concrete pool to erode. If it's too low in a vinyl or fiberglass pool, it will have no effect, so don't worry about it. Pool dealers will still sell you calcium to add to vinyl pools, because they like selling stuff, and have been told by the chemical companies that you need to have it. They don't know why, though.
Shock treatment for the green part. If it is still cloudy you can add a clarifier sold at your local pool supply.
Add more chlorine
Potash
potassium aluminium sulphate
Adding algae control to the pool skimmer helps to disperse the chemical and coats the filter media.
add a PH reducer chemical
This will depend upon whether you have a plaster finish or not. First test the water to determine if you, in fact, need to add acid. If the test indicates that you need acid start with small quantities. Maybe one to two cups of acid. You don't have a lot of water to deal with here and so you could bring the water to acidic conditions easily. Wait about 20 min. for the circulation to distribute and test again. If the demand for acid is still there then you did not add enough acid and will need to add more. Continue this until you reach the goal of about 7.6. Test again the next day to see if the pH has stabilized. If so, then that total amount of acid that you added was what the pool demanded at that time. Each time most likely will be different. A vinyl lined pool can usually have a lesser demand for acid. Ken
