I am having some stubborn mustard algae that just won’t go away. I need help to kill it.
These are the details:
Pool is 30k Gallons. Below ground plaster kidney shape with a small round spa. The pump has been circulating for 48 hours none stop. The CYA is at 60, the PH is 7.0, FC 25 or more (test taken by strip at pool supply store). I do not have an accurate FC number due to the limitations of my Taylor k2005c testing kit.
1. First day I used 3 gallons of 12% Chlorine and 9 oz. of swimtrine plus algaecide (copper 9.3%)
2. Chlorine and the algaecide removed about 50% of the algae.
Since the chlorine & algaecide did not work well my local pool guy advised me to use 5 lbs. of algae destroyer concentrated stabilized chlorinating granules -99 %TRICHLORO-S-TRIAZINETRIONE. After two days of brushing 3 times a day the 10% of the yellow algae still there.
I have read most of the information regarding the algae at this site.
I welcome any input regarding my options to get the mustard algae out.
