As a newbie to this forum, I have been reading about the BBB method and all the pool store chemicals, we do not need to use, we have always used algecide regularly in the past, but I havent' seen much mentioned about it in my readings here so far. Is it recommended to regularly add algecide to the pool? I have purchased some of the hTh algecide that is supposed to work for 90 days, but haven't added it yet.
