Remove impurities in the pool with high-pressure cleaner
I had very strong contaminants in the pool. Caused by the addition of copper sulphate. Then I really tried everything that gives it to chemistry. From vinegar cleaner, Kalkentferner to citric acid- everything has brought nothing. I was almost getting used to buying a new film. But is not that cheap. Then I thought, if so, you can try something else. So I've just made my high-pressure cleaner ready and started. (Has about 100 bar) And what do I have to see - everything sparkling - really everything away. The pool must of course be empty. Saved a lot of money, it costs a maximum of a little water and some electricity. Had saved even more, if I had done the same, then the money for the useless special cleaner would still be there.
