I am starting to get yellow staining on the tiled pool floor, particularly on the steps and at the shallow end. It appears only to be on the floor and not on the walls. I assume it's calcium as we have very hard water here. I have tried scrubbing to no avail. Is there anything I can do to remove it or, failing that stop, any further build up?
We recently had some light yellow/brown stains on the bottom of our pool. From the shape assumed it was caused by leaves. Certainly wasn't algae. Very hard to remove but after shocking the pool and scrubbing with a wire brush we eventually rid ourselves of it.

I had 5 years of gradual cal build up on floor and walls of my pool that was 100% removed by application of hydrochloric acid (as advised by my local 'fontaria'. Pour in; Pump off for 48hrs, Brush and Re-brush with filter back on and plenty of flocculation tabs; Finally plenty of backwashing.
I am no pool expert, and was a little worried that I may have killed all the good bacteria in my sand, but there seems to be no ill effects and the pool surfaces are all like new now.
Thanks for your quick replies. Nizzo how much acid did you use? How did you introduce it to the right places - did you pour it through a tube or just pour in? Our Ph is very hard to keep stable at a low level and think this is the problem.
Oooh Hubby and I used to suffer from deposits at the bottom of our swimming pool for years. Since we installed a new outdoor shower and toilet, the pool has improved no end. The grandchildren now use these instead.
I am also very interested in those flatulation tablets you mention Nizo, where do you get them. Hubby could do with a few.
