You have a dark blue pool and the water was a clear green hue. Iron tints the water yellow and against a blue background will make the water look green. What kind of salt have you put in the pool. Some 'pool salts' are actually food grade salt and contain an iron anti-caking compound and will add iron to your pool. Solar salt is your best bet and less expensive.

No Mor Muriatic Acid is simply the brand of sodium bisulfate or dry acid sold by United Chemical . It is nothing special and the same as any other dry acid. It is the WORST thing you can use in a salt system because it forms sulfuric acid when dissolved in water which produce sulfates and sulfates are not good for salt cells!
Do not use vinegar or dry acid to clean your cell (your pool store is giving you very bad advice!), you use a 4:1 mix of water to muriatic acid as explained in the AquaRite manual on page 8,which I will quote:
Mild Acid Washing: Use only in severe cases where flushing and scraping will not
remove the majority of deposits. To acid wash, turn off power to Aqua Rite. Remove
cell from piping. In a clean plastic container, mix a 4:1 solution of water to muriatic acid
(one gallon of water to one quart of muriatic acid). ALWAYS ADD ACID TO WATER -
NEVER ADD WATER TO ACID. Be sure to wear rubber gloves and appropriate eye
protection. The level of the solution in the container should just reach the top of the
cell so that the wire harness compartment is NOT submerged. It may be helpful to coil
the wiring before immersing the cell. The cell should soak for a few minutes and then
rinse with a high pressure garden hose. If any deposits are still visible, repeat soaking
and rinsing. Replace cell and inspect again periodically.
