I would just like to thank Martin who went out of his way to help me solve the problems I had with the correct advice on applying chemicals to my hot tub. Due to bad advice I ended up with Folliculitis a terible bacteria which is formed when the water in your tub is not correctly maintained. You don't want it in your life I can assure you. I now have the perfect balance of bromine and water treatment in my tub just wish I had had his help from the start 12 months ago. Also thanks to John in the warehouse who supplied all my chemicals speedily the next day. So I would have given them both 10 Stars if I could. I would highly reccomend dealing with these guys!
