Hi David Just a quick note to say we are now mid way through our second term of swimming lessons in our new pool and the pool is coping fantastically well. We are now over 400 per week in the swim school and 450 school children per week and building! We have had many comment about our water clarity and our underwater photos show this off beautifully. We were very pleased with the initial work by your company in helping us to get our pool built and running in a very tight, 12 week time frame. Now the pool is very easy to run, our back wash, vacuuming, plant checks and water testing is all going very smoothly and the manuals are really easy to follow. When I have had the odd brain fade! it has been very reassuring to know you are only a phone call away, and can walk us through any issues on the phone. Keep up the great work FPC "Fabulous Pools with Confidence!!!. Best regards Ally Todd SWIMMING 0274741943.
