Dealing with black algae (Part 1 of 2)

[smallpooldad]

Sorry forgot one cautionary issue.

If you do empty your pool remember to use Ben’s Calculator for CyA and add about 4 ppm chlorine initially (never over 5 ppm), and check twice a day to maintain it there; as the CyA may take 3 – 7 days to work fully. Otherwise you may get algae and not just the black kind. Also adding Algaecide 60 will help but it might drop your chlorine level.
