Swimming pool starter kit

I'm not happy with this product I did not see mini anywhere in the advert and I notice the mini on the picture is slightly covered, I already have the floating clorine dispenser and thought the PH balancer would be a nice add on to my clarification routine.When I received the package I was amazed how small it was, I suppose if I had a paddling pool it would be fine but I have a 5000 gallon pool and I think this item is going to be hard pressed to do anything.
