Shock time?

[Thesil]

Hi I am new to the forum and just started the BBB method. Today I needed to add sine baking soda to bring my level up to 100. I am using new water cycler until I run out of it and then I will start with bleach. I noticed some green spots on the bottom of my vinyl and on the metal handrails. I need to shock, I suppose is day or night better

Shocking is a process that can take several days, even weeks. I would say that starting at night is better because you know that all your FC is being used for killing the algae, but the hourly FC checks and bleach additions might be more difficult during the night. Keep in mind you'll need to hold the shock level, not just a single addition, and it'll drop fast at the first few additions.

Thanks robert. I will be away for 13 days however and will only be able to shock today and tomorrow. I usually add 1lb per 10,000 gal. Should I add more!

I don't know what that means?

Read up on the shock process. It would be better if you wait until you return.

Between now and then, get a full set of test results and post the numbers up. Also please tell us as much about your equipment as possible.

You are also going to need a quality test kit with a FAS/DPD chlorine test to perform this process. The TF-100 is the one we recommend around here.

The only thing we recommend to use for shocking is bleach or liquid chlorine, because it doesn't add any unwanted chemicals. No powdered forms of "shock".
