Can someone please offer a suggestion? Last week, my 48,000 in ground pool turned green overnight. I took a water sample to the pool store right away. They said the pool was unbalanced and had mustard algae. They recommended the following:
Thursday: run the filter continuously until the pool is clear, increase the ph, add calcium chloride, shock, use a Bioguard algae killer called Banish.
Friday: vacuum and shock again, clean out the filter cartridge.
We did all of that and the pool is much clearer but it was still a little cloudy in the deep end. I called the pool store and they advised me to make sure that the chlorine was holding - it was still ideal - so we let the kids swim. The water was a little foamy when they jumped in and then they smelled a little fishy when they got out of the water! I tested the water again tonight and the chlorine is still in the ideal range. The ph was ideal too but I can't get a test result for alkalinity. My test kit instructs me to add the reagent until the water turns orange-yellow but the water doesn't change color no matter how much reagent I add. I read on line that I should shock again if there is a fishy odor but it doesn't make sense to me. Please help!
