Have posted before about this but wanted to try again and see if there is anymore insight with this. Will post test results after rant. Anyone know if it is possible to pass the OCLT while having mustard algae? Have passed this test numerous times now and am a bit confused. And yes, before anyone asks, it is mustard algae. All the characteristics are there and it won't go away. Have not done SLAM yet due to hot weather and wanting to enjoy the pool but the minute it cools down here, going to hit it hard. Test test results below.
