Use a microfiber scrubber similar to those used for car cleaning to maintain the pool waterline. The waterline is the most troublesome area as it collects oils, while the rest of the pool walls and floor can be scrubed by the provided microfibre broom.
Can I use tank water to fill the pool?
Yes, however not recomended. Additional chemicals may be needed to balance the water. Consult your local pool shop for localised advice and the best process
