Due to various issues, mainly long term travel commitments, I closed my tub 4 years ago. I am now ready to re-open it and have it up and running. I am concerned as over the last 4 years some water accumulated in the tub. There are no freeze damages and I am confident of that statement. What I am concerned with is molds/mildew and the long time sitting of stale water in the tub. It did have a bit of an algae residue. I have flushed it out with fresh water and drained it. My next step is to clean the tub with rubbing alcohol. I can reach all of the surfaces but what is in the pipes are of concern
OK, now what should be next?
I would think my first step is to decontaminate it. Other then the standard decontamination process that is on this site, it there another step or steps that I should undertake to eliminate any harmful bacteria that I have allowed to breed over the last 4 years?
I have purchased all new filters. Should I use the new filters in the decontamination process?
Is there a way to determine after the decontamination process that the tub is safe? I am thinking that after water balance, tracking FC usage with no tub use should be an indicator that the pipes are cleaned and free of bacteria or not. Is there a better solution?
I plan on going the Dichlor/Bleach route for sanitation maintainance. I properly disposed of all my 4 yr. old chemicals and have purchased all new. I also purchased a Taylor test kit.
Thanks for all the help and I will post up my results as suggestions filter thru.
