I've been holding off on the UCSB water lately, due to the rains, but mostly becuase I tested it for phosphats and got a reading of .25 ppm!!!! Has anyone else confirmed this? Before this wave of storms, it read 0 (or un-dectected). I'm womdering if it's becuase of the storms.. and everytime it's been a 3-5 days since it's rained, it rains again
