Hey everyone. I've been lurking for a little over a month now reading and learning, trying to get set up to use the BBB method in my hot tub. I haven't started doing it yet, still just using the dichlor, ph & alk up/down the spa store sold me, but have a question I need answered so I thought I would go ahead and ask here. I am leaving out of town next weds for Cozumel and will return the following weds. As of now even if we aren't using the tub I have to add about .25oz of granuals a day to keep the ppms up around 2-4. I was thinking about shocking the tub to 10pm the morning we leave, don't head out til about 10am, and running the jets til the water gets back down around 6 or so before putting the cover back on. My question is there anything else I can do to keep the tub from falling below 1-2ppms before we get back?
Here are my test results from this evening.
Hot Springs Sovereign 355g tub.
Water temp at 95* right now for the summer and in summer heating mode. Also using a thermal blanket to help evaporation.
