After a big storm lasting a few days my pool was filled with dirt and leaves, my total chlorine was down to zero, and some algae started to grow on the sides. My numbers looked like this:
I have a bunch of store brand (non-BBB) pool chemicals that I want to start using. Last night I added some algaecide and some non-chlorine, potassium monopersulfate-based shock. The pool water is looking better and the algae is starting to disappear. I also added some stabilizer to get the CYA up.
After about 24 hours my numbers are:
The shock freed up a tiny bit of chlorine so some FC actually registered. It's probably too soon for the stabilizer to show up however I think it or the rain this morning moved the pH down. I plan to add some baking soda to get the TA up to 100 and hopefully raise the pH a little at the same time.
Here are my questions.
1. How do I know when I'm done shocking and treating for the algae or when I need to add more? The shock instructions say to add 1 lb. per 10,000 gallons to destroy contaminants that have accumulated in the water and to reapply weekly to maintain water clarity. The algaecide says
Maintenance Dosage (weekly):
Add 4-8 oz. per 10,000 gallons.
To Treat Existing Yellow or Green Algae:
Add 16-24 oz. per 10,000 gallons to a pail of water and distribute.
This implies that I'm done treating with the shock and algaecide until next week.
2. How do I get my chlorine up? I have trichlor tabs; however the instructions say to use them after you get the pool balanced. I don't have any other chlorine products like dichlor or chlorine based shock. Should I just put some tabs in the floaters anyway or should I kick things off with some good old liquid bleach to get the ppm up to 4.0?
