Hi All, I have a plaster pool and have several stains primarily in the deep end and closer to edge of pool. The stains are about 1 to 2 inches in diameter and they are yellow green colour. They are also rough when you touch them and they feel like they are attached to the pool surface. I have...

I made a silly mistake of not reading the instructions and added 5 Kg of a product called Refresh which is borate. What a did not realise was this product increased PH. After 2 hours checked pool and had white blochy stains where I had pured this stuff. I tried brushing which did nothing. I...

I have 65000 litre concrete plaster pool with a SWG unit and I have the following numbers as per my Taylors kit. CL=1.60 PH=7.7 TA=100 CH=130 CYA=0 Water temp 16 celsius My Lsi index is -.42 as this is not too bad as water will warm up shortly. Is my PH high and should I be trying to get PH to...

Sorry my mistake CYA is only about 40 to 50. I have an automatic SWG unit for PH and chlorine so I try and keep CYA at no more then 50.

Thanks for info will investigate further. I don't think sensafe meter is wrong because sensafe was 60ppm and Taylors was 50pppm. I was a bit alarmed that TA was a bit low s I dumped about 2Kg(4.4 lb) and took another reading sometime later. Sensafe was 80ppm and Taylors still 50ppm. My pool is...

I have a Taylors FAS DPD test kit. I drop five drops of final solution and colour changes from green to red and stays like that.

I have a Taylors kit which is about 9 months old and lately the TS reading is consistent at 50ppm. To increase TA I dropped Bicarb Soda and tested with sensafe meter which read about 80ppm but Taylors kit still stated 50ppm. Also had water tested at pool shop which cofirmed the sensafe...

I have the Zodiac Tri Pro (Australia) and I have similar problems with continuous chlorine generations. The technical staff suggested calibrating the orp sensor when chlorine was at 3ppm. This made no difference at times it would continue making chlorine and at other times it would stop and...
