Just closed down my pool. I have a Turbo-Cell-15, and I was planning to take it inside for the winter. Upon removing it, I immediately noticed a really bad buildup on the plates. I assume this is scale formation and/or calcium deposits? Please keep in mind that I just bought this pool in August, and this is my first pool. I'm just getting everything figured out. My pool is plaster. I tested the pool water alot in Aug/Sep as I was learning about pool water chem. Ironically, the Ca Hardness was low when I began. I think it was around 100, and everything I've read says you want to shoot for somewhere around 250ppm for a plaster pool (200-400 being a safe range). So, I did add a good bit of "Balance Pak 300". (I was careful to add it slowly over several weeks while testing in between each application. I would add 3 lbs here, 5 lbs there, etc. Brushed it in at each app. Ended up adding close to 25 lbs I think, over several weeks. Ca Hardness was around 250ppm at my last reading.)
Also, FYI the pH runs high in my pool. It was in the neighborhood of 8.2-ish when I took over maintenance from the weekly pool company service. He was very unconcerned about 8.2. He said the pH is high in a salt water pool and not to be concerned. I tried hard to bring it lower over many weeks using dry acid. I added quite alot of it, but it proved very difficult to budge. I think I got it down to 7.8, but it went back to 8.0. I haven't checked it in awhile.
Sorry for the long post for such a short question, but I like to provide as much detail as possible. Question is, is the buildup just standard scale formation and/or calcium deposits (same thing?), and are there any other "bigger picture" concerns to draw from this bad buildup?
I think I have a good idea of how to clean the cell from other TFP posts and from the Aqua Logic manual.
