I'd like to ride out whatever path I started on when adding the Line Cleaner (7/15) and see where it goes. Oxidizer level is coming down albeit slowly. When it gets to where I've typically had it and if there is still a smell, etc., then I'm thinking of doing at most a partial drain. I know it'd be a good time to fully drain, but if we keep these sustained high temps it won't do the plaster any good for the length of time it's exposed, plus I'm behind on so many of the usual summer maintenance issues around the property. I can't work out in 90+ degrees to do much of anything like I could 20 years ago, or else I don't feel too well the next day or so.
IF the water settles down back to a 'normal' state, I'm leaning towards finishing the season with baquacil and then decide over the winter. I was really hoping to see how things worked out with the Line Cleaner but then - from everyone I've talked to - I screwed up by adding all the other stuff almost immediately after instead of waiting 24-48 hours. So not sure this is a fair test of it. I DO consider Line Cleaner the last attempt to continue on with biguanide, so a turning point is definitely looming. The random element, of course, is whether or not I still would have wound up with this rather bizarre and totally unprecedented water situation even IF waiting to add the CDX and Oxidizer. Yet another variable is having added the heavy algae treatment the day before the Line Clean - surely WAY too much stuff too close together. Quite honestly, I'd rather put more money and time into a conversion in spring with the pool full of water then run whatever risk there might be to the plaster by draining this summer. There has been no trace of mold whatsoever, and the current filter cycle is now 2 weeks - the longest of the entire summer. As posted in another thread I started, the ammonia in the water is between .5 and 1 ppm - so I don't know if that could be considered high or not. If the water does not normalize fairly soon, however, then I am looking at doing a partial drain but returning to finish the season with biguanide. So much depends on my schedule next spring as well. With this COVID situation and all the unknowns it holds, my travel schedule is being decimated, so trips that were scheduled for this year are all being moved to next year - no idea how that might even impact when I open the pool and how much time available to work with it especially in the event that we would have to schedule one of the trips during the early part of the summer. Too many variables at this point to commit to anything. Thanks for asking though. Taking it one day at a time for now. I increasingly understand, as time goes on, what my Dad always meant when he said the older you get the faster the years go. I'm finding myself swamped with work I haven't even touched yet and it's already near August. (I KNOW what you're thinking....by at least simplifying the pool schedule via using chlorine instead of baqua, it would leave more time for other stuff!!)

I get it...and believe me....it (conversion) is now a more serious contemplation of mine than it probably ever was. See how things go .
