I bought some Ahh-some off of amazon the other day and I am getting ready to use it to clean my hot tub. Here is what worries me though. I inherited this spa from my parents and while they maintained it well, I am highly doubting they ever deep cleaned it. Currently I am having no issues with maintaining perfect water balance and clarity but I do feel a deep cleaning is in order. I do not notice a high amount of chlorine usage but I am using a SWG. I live in the country and I have well water as my fill source so I cannot do 8 or 9 drain and refills to completely clean the tub at once. I can maybe do 2 or 3 complete refills at a time because I am afraid my well could get drained down. Here is the question, if I do a couple of rounds of ahh-some, then come back a month or so later, do a couple more rounds, could I continue to use the tub in between? My work schedule is hectic at times and while I can do a couple of rounds in a row, I can't do 8 or 9 in a row and I fear that is what it will take to get this thing purged. I'd like to use it in between chances though and want others opinions. If I shock it good in between will that help? I read several others experiences and it makes me apprehensive about trying this but in the end I know it'll make me feel better in the tub. I like the suggestion of putting the ahh some in, running the tub, cleaning out the gunk, letting it sit and soak and then coming back and running the tub again before cleaning and draining. Any additional advice is welcome.
