Another year of start up problems..lol...My pool was almost completely drained in closing by mistake by my loving brother. I had uncoered it this year to find a little algae so it took 2 days to fill it back up. In that time the algae grew and our water has alot of iron in it. So my question is do I try to kill the algae first or get rid of the iron first? The metal out stuff says you cant have chlorine in the pool when using it .
