Thank you

I live in Andalucia in Spain where summer temperatures can reach 35 ° C – 40 ° C (95 ° F - 105 °F). I have a concrete pool 6m x 4m (20ft x 13ft), 170cm (5’6”) at deep end, of which 30cm (1ft) is below ground. Originally painted the walls & floor are now covered with mosaic tiles. The water...

The air temperature is 75 degrees atm. Should I buy a thermometer to check the pool temp? A reading of 6.6 does equate to 3400 ppm. Should I start adding salt gradually to get the reading up to that level. I've read on a couple of sites that the chlorinator will not function properly unless...

Yes, of course. I'll wait & see what happens. Last time I switched the SWG off for 3 days the FC dropped to 2; however the pH was unchanged at 8. The sun is getting stronger though so.......Thanks again

Thanks Richard I think I'll wait a few days and see the outcome of switching off the SWG again. Perhaps I need to give it more time....... I wonder if i should put more HCl in now, or wait to do that. Thank you for all help!

Thank you again. I have switched off the SWG and will wait to see what happens. I did do this for 3 (sunny) days last week and, by the third day, the Cl had dropped from 3.0 - 6.0 to 2.0 - 4.0. The pH level during this time was unchanged despite the addition of 3.5 litres of 24% solution HCl...

Thank you Richard That was an interesting link you attached. Tbh I couldn't follow all the detail but I get it that the pH readings, using phenol, can be false if Cl levels are high. I will do as you suggest and switch off the SWG for a while. That should encourage the CL level to go down...

Thanks. The pool is outdoors. I've checked with a couple of friends and they don't use CYA either. The control panel for the chlorinator is also saying that salt levels are low. I am using test strips. And, you're right, anything more sophisticated is very hard to find here! M - - -...

Thank you For the salt level I am using Aquachek Test strips. According to the chart on the container a reading of 4.6 equates to 1450 ppm of salt. As for the pH I'm using a test kit similar to Analysis of Water Pool - Swimming Pool Water Test Kit - jardiboutique: Amazon.co.uk: Garden...

Hi. I live in southern Spain. I'm renting a villa with a salt water pool. There are no manuals and the landlord is very vague about how to maintain the pool. I have an in ground salt water pool; with concrete sides & base and tiled surface; capacity = 65 c.m. (17k US gallons, 14.3k UK...
