Ive been testing daily/weekly and noticed a discrepancy with the daily chlorine test vs the free chlorine test from my Taylor Kit. After 2 days of heavy rain my FC is 1.5 which i know is very low but my daily chlorine test (yellow) has a much higher reading. Ive also noticed black marks that reappear on the baja shelf after i brush it. It remains clean for 2 days and it begins to reappear. Could this be black algae? Mind you this is a brand new pool and salt was poured in a couple days ago by the builder but the Ichlor has not activated bc of cold temps. Thanks for all your advice TFP amigos!
