I am looking to discuss a water chemistry problem we are facing relating to calcium precipitation. I wonder if you could point me in the direction of someone in bristol who may be able to help us with this? I have tried a wide-range of people but it appears to be a very niche problem.
We have an algal problem in one of our recent swimming pools (unfortunately there was a phosphate contamination issue). Here, algae are forming a biofilm on the side of the pool. The main issue, however, is that the algae are causing calcium carbonate/limescale to precipitate out of the water at alarmingly high rates. We have a reasonable understanding about how this happens, but not why it is happening at this pool and at such an alarming rate.We are desperately trying to find a way to reduce the precipitation rates within the pool and we are unable to answer this question ourselves.
I have also attached a small spreadsheet containing some of the chemical analysis. Here, 'jaggards farm' is the pool with the precipitation problem. Is there anything among these data to suggest a reason? Any help/advice would be much appreciated. As would forwarding this email to anybody you may know who may be able to help.+23 Other Responses
