Hi,
I am based in Kuala Lumpur, Malaysia and pool care here is very primitive and basic.
I run a small swim school catering to swimming classes for mostly babies and preschoolers. My pool is 4 feet deep and size of 40 feet x 25 feet. We have a load of around 700 bodies in the pool each week (parents need to be in the pool with their babies).
We have 2 SWGs and pump is running 24/7. It has been quite tricky to care for our pool since Day 1 and we have changed a couple of pool operators. There are no test kits available here except the OTO test that we are using. The test kits that are recommended here (Taylors and TP-100) cannot be shipped to Malaysia due to custom laws. The chemicals available here are very basic ones only. There are no pool shops to get pool water tested in.
Recently my pool has had a green tinge but clear water for the last month. 5 of my swim teachers have complained of dry, itchy skin breaking out in a rash. kids have stinging eyes from opening the eyes in the water without goggle. We spent $80 to get our pool water tested in a lab and these are the results.
PH 7.35
TDS 5002 mg/L
Free chlorine 0
Chloride as CL 3356 mg/L
TA 67 mg/L
Hardness 155 mg/L
Total Coliform 23 MPN/100L
The Coliform present is worrying and I am thinking should I drain the pool and replace the water? I don't know why there isn't any free chlorine when my total chlorine is high. I don't know what else to do. My Total Chlorine according to the OTO test is 3.0
Thanks
Joanne
