CHill;
I'm sorry, but I don't know!
It's right about at this point that I often throw up my hands on threads from posters not in North America. You don't have a decent test kit, or trustworthy test results; I don't know what to tell you to go buy, and add, and so forth.
I have no idea whether your 10 ppm means 10 ppm (actually & exactly) or 10 ppm (that's as high as the strip goes, but really 50 ppm) or 10 ppm (but really 5 ppm).
The only thing I can tell you is that USUALLY, when the pool is still green, you need more chlorine. Once I years ago, I encountered algae that didn't die till I reached and held 50 ppm of chlorine -- cya was about 50 ppm. But, because there is so much I don't know about your pool, I'm going to stop short of recommending that you add more chlorine. That's PROBABLY what you should do, but I don't know.
