Hey guys, about to open my pool shortly here in Northern Virginia. I was curious if i should be testing for metals in the water after opening and balancing the chemicals, as far as i know i didn't have any issues with metals last summer (first year of pool). Also, any need to add any algecide or other chemicals to the water during opening. Last year all i used was CYA, bleach, baking soda, and sometimes borax. Thanks, and i look forward to being an active member on the forum this year again!
