Greetings. Just finished what I think was a successful ascorbic acid treatment, thanks to the directions provided here, which I followed precisely except I have not used a culator because I don't have a sock for my skimmer basket. I used 2 bottles of Leslie's ascorbic acid followed by the Protem (?) metal out once I got my chlorine down to 0.
The water is clear, the metal stains that were on my steps and liner are gone, Ph is back up to 7.2, and last night I added a bottle of bleach (slowly, over a few hours).
This morning, water looks good and here are my readings:
Alk: 80 ppm
My question is: How long before I can turn on my chlorinator? I use tri-chlor pucks. I know my cya is high and needs to come down, but can I put the chlorinator on a very low setting now and gradually turn it up to where it normal position? I am not comfortable using liquid bleach as my main chlorinator.
Also, with regard to prevention: I don't use well water and my heater is about 4 years old. I'm not sure where the metal came from. The staining started last year, mostly on the steps, but it really wasn't horrible and I was able to get most off with stain out (direct application). When I opened this year, after shocking and a few days of the chlorinator running too high, the stain on the steps was unbelievable and had spread throughout the liner. I have a culator and plan to put it in the skimmer once I get skimmer socks, later this week. Is this more effective than the Metal Free, or should I be using both as preventative action? Do you recommend once a month?
Thanks again. This forum has helped me quite a bit since I became a pool owner 8 years ago, but this is my first real problem, and hence my first post. Everyone's expertise and willingness to help has been much appreciated.
