many thanks for your previous advice, much appreciated.
I recently did a ColorQ test on the (Desy)pool water (It is still in Winter mode with the cover on and was treated with winteriser in October) The chlorine level was zero. Having suffered serious algae problems during the last 2 years, before I tuned in to your advice, I am determined to do better this year!
Shall I add some diluted choc or javel now (before removing the cover and starting the pump) to up the chlorine level and start off on the right foot this year?
For info the pool was no problem for the first 13 years of operation, with 1 new liner and 1 new pump 3 and 5 years ago respectively. For the past 2 years I have set up the pool in early May with all the levels corrected before returning to UK leaving our long standing pool maintenance man in charge. He has then called me a month later to say that the algae is out of control, despite several gallons of anti algae being poured into the pool. Last year I went over with my recently purchased ColorQ, changed the water completely, and made sure that all the levels were correct. There were no more problems last year. I had been assured that the ch and ph levels had been maintained correctly.
i am anxious to avoid the problem for the third year running??
