New to the forums - thank you in advance for the advice!
We are on day 6 of treating the dreaded mustard algae. A little pool background:
40,000 gallon in-ground pool w/ a spa inset.
Triton 2 tr-100 sand filter w/ zeobrite
We started last wednesday, July 11th
Added 4 c Muriatic acid
Waited 1 hr, added 8 lbs Biogaurd Maintain CLC3
Waited 1 hr, added 2 quarts Biogaurd Banish
Soaking all pool toys & equipment
Running filter 24/7
FC spiked @ 30 and has held high throughout treatment
7/14 Added phos-free
7/16 added second heavy dose of Sea Klear
Analysis as of 7/16
Saturation index -0.7
Adj. TA 50
Total Hardness 149
The trouble continues, though we are seeing a bit more water clarity, it is still very green, with patches of brown stuff (which I believe to be the dead algae) on the bottom.
Our pool store is advising us to just let things ride for the next few days, would greatly appreciate a second (or third, fourth, etc) opinion.
Thanks and cheers,
