Ok- so make your CYA 40 round up- the CYA test is non-linear - you need a separate test kit for the the salt test so don't worry about that at the moment. You need to get some chlorine in there pronto- can you also give us a CC reading.

Thank you masters ....
Beautiful, now we need to know volume of your pool as it is primary parameter to calculate amount of chemicals using The Pool Math You can go there and play yourself, it even 'understands' metric units. Then you immediately become one of us, it's not a rocket science. As was already mentioned you're awfully low on FC but to calculate how much chlorine is needed the pool volume is required. You can calculate yourself, post the amount here and someone will verify it for you if you're not sure. The chlorine source (bleach) comes with different concentrations so that needs to be entered as well. Please use plain unscented non spalshless bleach, the cheapest you can find. Please pay attention to the concentration as $4/gal at 12.5% is much better deal than $3/gal at 6% and it's less water to haul around.
But... I don't know the volume of pool ... It is like a ...bird...and the bottom slope deeper from onleft to right ....What can I do ?

The same Pool Math page has section to estimate pool volume of the most common shapes at the bottom, you need to know it with +- 20% accuracy for now. Have you bought the bleach? If I were you I'd run and bought few gal right now while the stores are still open .
