    Green Algae

    Please help. For some reason i've got green algae on my pool liner. My numbers from the test kit show cya between 50 & 60. I have maintained fc at 7, per chart, ph 7.6 to 7.8,alkalinity 70 to 90. I've used BBB method since early May. I have 2 quarts of Aqua Chem algecide,which i haven't used since switching to BBB in May. Will it be ok to use this instead of bleach. I hate to waste these 2 quarts. I leave my pool open all winter. I keep the CL level up all winter. Thank's again for all help.

    Algaecide will not fix your problem. You need to shock your pool.
