Always shock visible algae?

[Whatrymes]

Sometimes I find visible algae hiding around my ladder. Do I need to shock when I find this? Everything else is pristine.

FC = 6.0
CC = ~.2
pH = 7.6
TA = 120
CH = 250
CYA = 50
ONCT = < 1.0
. . . and sparklin' clear.

Thanks

Yes, shock.

You should also be sure that while you are shocking, you need to brush those nooks and crannies that allow algae to hide out with good frequency. Brushing better exposes the algae to the chlorine in the water.

If your ladder is removable, then remove it and hit the inside hard with bleach to kill off any algae inside. That should prevent the algae from coming back.
