Hi I see this is an old thread nevertheless I would love the answer. I have the exact same problem with the hard calcium deposits in my pool. The picture in his thread resembles the finish of my pool and also the "bird Poop" looking hard as rock white calcium deposits. I have been spending a small fortune going by the local pool shop remedies, all unsuccessful. I am curious if this problem was ever resolved and how did you do it? ElementZero or anyone who has had success in the removal of hard calcium lumpy deposits please give me the answer!
The strange thing is until now I have never seen this in my pool before. The pool is about 12+ years old. The water is really clear and even since adjusting all the water according to the recommendations the "calcium" is not igoing away and the pool is even "growing" more hard lumps everywhere.
Thank you any feedback is much appreciated.
Kind regards, Robbie
