I just found your forum today and have a lot of changes to make. I have already shocked it yesterday and today with 2 lbs shock each time and added EZ Chlor Mustard Algae Plus. Not the best of choices I guess after reading, but was desperate to get started treading while the bloom was early. I have an extra question I'm not sure is related to the algae or pool construction.
After we give the pool a good scrub (yellow gone) we can still get a milky white substance to rub off with our hands. I noticed this today and we had it a few months back as well. Also I remember it a couple of years ago when we were just getting started.
Could this be dead clinging mustard algae or paint/plaster coming off sides of the pool?
FC - 10+
CC - water is a bit cloudy, but my strips can't test for this
pH - 7.2-7.6
TA - 80
CH - Calcium Hardness was in normal range last time tested a couple of weeks ago
CYA - 100, higher than usual, but I have also added 4 lbs shock in the last 24 hrs.
Currently using 4 way test strips. I'm sorry that I don't have complete water chemistry analysis, shop is closed until monday and I feel like the other pool store just wants to sell me chemicals. We have been battling mustard algae every year, several times each year. This year seems to be the worst, we have had a bunch of rainstorms that I think are bringing in the algae.
Might help to know that we also have a leak somewhere as we have to add water, usually on a weekly basis.
Thanks in advance for your help, I will try to be patient with my pool and we will start implementing the pool school pointers.
