Given the warm days in the last few weeks, I let myself carried away the sand fill before and to serve a probationary irrigation in winter actually already moored pool. Even at times to test the new sand filter, because if these shortcomings have, you lose almost half a year warranty and 30 days money back is also nothing more. So connected and this new plant sand clean. Everything done exactly as prescribed and: It works fine! Have again replenished the pool floor and it was three days later to find no sand on this. At least not visibly. This makes the sand what he should and is recommended. The sand filter incidentally also ;-)
