Mustard Algae continued...

[CUTURHAIR]

Ok, I must still be battling mustard algae. I dropped from 15ppm to 11ppm overnight, last night. We did get a lot of rain yesterday, so that could be part of it, but I feel like I am still seeing small traces of the mustard algae. I didn't add a second quart of poly 60 algecide yet. It has been about 9 days of trying to keep chlorine at 15, since returning from vacation. There were some days when I couldn't stay on top of it, but for the majority of it, I am checking and dosing at least 3 or more times throughout the day.

So, do I just keep doing this longer I assume? I am going through bleach like crazy! Brushing and vacuuming as well.

My Ph is 7.5
Alk 90
CYA is about 35 now

Anything else I need to be doing/changing?

Thanks,
John in NC, TIRED of the mustard battle!!
