I recently rehabilitated the pool at my house in a bid to get fit by swimming! My pool has a marble base and the only chemicals I added to the newly borehole filled pool was the Blu52 weekley maintainance pack which comes with a booster and weekly chlorine pre packed doses.

I do not own a test kit and after all the research I had done, I was very keen to test my water and get my ph, metals, chlorine etc right. On taking my water to the local pool shop, the guy there advised I add a number of things to the pool. Amongst them where :
1.Pool acid for the Ph
2.Chlorine 2kg
3. Stabiliser
4. Copper (said it would make water clear and nice and 'Blue')
5. Something I don't remember for metals in the pool (since my water is borehole water).

I did more research and went on to add only acid to the pool. On testing the water again, the ph was perfect at 7,2. Chlorine levels however where at almost zero. Up to this point (6 weeks) the pool had maintained its colour. The pool shop guy however insisted on adding the copper sulphate (bluish crystallite form). I went on to do so as advised and since adding it my pool has a very thing metallic film right on the surface of the water and despite constant filtering surface water is also foamy thus a bit cloudy.

I have read countless pleas for help on the forum of people who have had problems with copper(wish I had found you earlier!) My pool surface seems hardly affected and besides the tin metalic veil and foamy look on top the water underneath seems quite clean. What can I do to to get rid of it. my pool is approx 50 000litres and I only added about 500-800 grams of the copper.

Also help with a general maintenance plan. Apart from the copper incident despite low chlorine levels, my pool had behaved quite well.
