Curing the Pool
   Many pool enthusiasts feel that it is an aesthetic necessity to paint the floor of a pool a dark color for the illusion of depth. A dark floor does give this illusion, and it will also make the pool surface reflect surroundings much more clearly, but painting the floor is not necessary.
    In the course of a week or so, fine siftings of soil from the planting boxes will have covered the floor and colored it up to suit the most exacting water gardener.

Best Curing Treatment We Know

    If you will excuse a fellow a certain pride of craftsmanship, I'll describe this particular curing treatment as the best one I know. It is a treatment we developed at the Fisheries, and apparently it has worked perfectly for the hundreds of customers to whom we have recommended it.

    1.Fill the pool to the brim and let it set for five days.
    2.Drain the pool, refill it, and let it set another five days.
    3.Drain the pool again.
    4.Mix up a solution of 1 quart of ordinary kitchen vinegar and 10 quarts of water.
    5.With a stiff brush (an old broom does splendidly) and generous sloshings of the solution, scrub vigorously over every square inch of the pool's inside surface. Mix more solution if you need it. The surfaces may bubble up a bit as the vinegar works on the free lime, but don't worry, it will not weaken the concrete.
    6. Rinse out the pool with a brisk stream from the garden hose, and it is ready for goldfish and water-lilies.

Subsequent Curing Treatments

    Ordinarily, a sturdy, well-constructed pool needs curing only once, and that is when it is new. However, an extensive job of crack filling, an addition to the pool, anything which brings pool water into contact with an appreciable amount of new concrete, will necessitate another curing.
