Hello,
I am new to this forum and new to pool maintenance, I am amazed at the volume of material that is available to help me but am not clever enough to sift out what I need to know.
I live in Thailand and have an inground pool, it is approximately 12 meters long, kidney shaped with an average width of about 4 meters. The lowest depth of water is 1.6 meters and 1 meter at the shallow end. I calculate the volume of water to be 13000 US gallons but could wrong! You maybe able to calculate it more accurately. The pool is of conrete construction with a fully glazed tile floor and walls. Our average temperture during the day is roughly between 30 and 37 degress celcius.
I have a sand filter with a 1.1kw pump to run the system. Water that leaves the pool is collected around the perimeter through a slotted plastic drainage syestem that returns the water to the charging tank. I am told this is not a skimmer system.
I have been using a droplet method for checking the Chlorine and Ph content in the water. This method shows coloured levels of each chemical and the test checks always turn out to be on the low side.
My main question is how much of each chemical do I add for each check level to get to the right amount required for clean and healthy water.
The Chlorine level is graded from 0.3, 0.5,(add) 1 to 1.5 (ideal) and 3.0
The Ph level is graded from 6.8 (add) 7.2 to 7.6 (ideal) 7.8 to 8.2 (add acid) what acid do I add if needed, never has been yet.? In these temperatures how often should I test the water?
I checked the pool today and had a chlorine level of between 1.0 and 1.5 (ideal) The Ph level was in the 6.8 level, How much soda ash do I need to add to get to the right amount.
I note from reading the material contained in the water testing section that there a few different methods for checking chemical levels, which would be the best for my use in the area and temperature zone where I live?
I have been sold Trichloroisocyanuric acid 90% min as Chlorine produced in Japan and Soda Ash (light) NA2 CO2 99.2% min.produced in Korea. Are these suitable? We live in a very rural part of Thailand and getting supplies of chemicals can be problematic, a trip to Bangkok (800k's) there and back will probably have to be undertaken.
As I stated previously, I am not blessed with a naturally high degree of intelligence and would hope that I do not need a diploma in chemical engineering to understand what I need to do. So, if help is available can it be presented in the most simplistic manner possible.
I expect the answers to these questions are probably somewhere in the Pool School forums but I have not been able to find them.
I do hope that I can get the information I need and any other suggestions that will help
Thanks for taking the time to read this.
