Use PoolMath to do the dosage calculations for you.

Your CYA at the top of the recommended range, so you have to stop using them. Never put them in the skimmer without the pump running. Your CYA will not drop just because you stop using pucks.

With proper FC levels, you never have to "shock" or use algaecides.

Responses are in red and blue

so my chlorine is at 1.5ppm how many litres of chlorine do i need to raise it 1ppmThis all depends on the chlorine strength your using. There is 6% and 8.25% bleach, and 10% and 12.5% liquid chlorine. Either way, the pool math tab on the top of the page can help you with that. 1.5 or even raising it to 2.5 PPM is to low for you 50 CYA. You've been here since 2013, I assume your familiar with the CYA/chlorine chart?

also my stabilizer level is 50ppm, should i remove the stabilizing pucks so that the levels drop? also should i place is floater or in skimmer i notice in skinner they get used up quickerYou should remove the pucks so it doesn't go any higher, but the levels don't just "drop" they get reduced only when you add fresh new water either after draining, backwashing or splashing out...replacing water after evaporation won't lower it any either. You should not place them anywhere, at 50 CYA you should not be using them anymore unless you are using a SWG and your trying to get higher CYA levels.

how often should i use algicide and shock the pool? Usually, and with proper care you can never need to shock, and algicide is not necessary or really recommended using the TFP method.

They refill bottles for me. So this does not sound right 1000ml of 10% bleach will raise the pool 1.1ppm?? Is that what the stuff from pool store is considered?

I would GUESS 12.5%...at least in the US, it seems pool stores carry 12.5% liquid chlorine, big box stores like home depot, wal-mart carry the 10% liquid chlorine, and the 6% and 8.25% is household bleach strength.

Looking at your first post, and your signature... Your post says 85000 litres and your signature says 13800 gallons..

85000 litres = 22454 gallon

13800 gallon = 52239 Litres

Not sure which to use.....

You need this: http://www.troublefreepool.com/content/165-getting-started

Most people test daily and add daily. The cheap kit from walmart, homedepot ... will keep you from running to the pool store daily but it is what it is, a cheap kit that will do some of the needed testing but not all.
4ppm FC is the lower limit for your level of CYA. You want to try and keep it around 6ppm and not let it get below 4.
If you know you are going to have people over or a party then that day you might want to go to 8 or more depending on your experience. This is where keeping a log with short notes on temperature, number of swimmers, sun-rain ... comes in handy. You can "see" in your numbers what was changed from one day to the next with a number of people in the pool. You can tweak your pool chemistry in relation to what you've learned from other "swim parties".
