I'm new to this forum, and hope this is the correct forum to post this thread. I am standing by to take flack for allowing this condition to happen in my pool. But I will admit that I'm not a good chemist, and am trying to get better. And, I've searched the interweb extensively trying to find a way to resolve this issue. That being said, the issue I have is widespread calcium buildup on the (marbelite) plaster. I can't find picture examples of it or I'd post one. It's not calcium deposits here and there. It's throughout the pool. It's caused the plaster surface to become quite rough, and because the calcium isn't truly white, it makes the pool have a turquoise-colored appearance rather than a blue appearance. We've lived in this house about five years, and I had the pool acid washed a couple years ago because it had happened before. But I guess my ignorance let it build up again. The water is clear, and pool in general is otherwise clean. I just need to control the calcium better. But my question is...is there a way to eliminate this calcium without draining the pool and get the plaster back to white? For example...while the pool is closed, if I brought the pH way way down, and scrubbed daily...would that get the calcium off? Perhaps something else? Or, am going to have to drain again and have it removed another way?
