SUPPLEMENT TO McHENRY PLAINDEALER-PAGE 4-FBIDAY, APRIL 18, 1975 Get your pool in shape early As warm weather ap proaches, swimming pool owners should be planning ahead, to assure them selves that the coming months will be enjoyed with a minimum of main tenance problems. Few pool owners, however, know as much as they should about pool main tenance. Yet this knowl edge can save time and money, and make summer swimming a pleasure. First, remove any pro tective winter covers from pool and equipment. If pool was drained, sweep the inside and surround ing areas clean of debris and dirt. Then inspect ex posed surfaces to deter mine if any cracking of walls or floor has occurred or if painting or refinish- ing is needed. Examine all valves, controls, and pipes for obvious deterioration. If all seems proper, turn on water to fill empty pool. Again examine all exposed valves, controls, and pipes for leakage. Dried pack ings and flaskets may cause minor seepages that will stop by themselves as they absorb water and ex pand. If not, tightening with a wrench or replacing packing will be necessary. If any major leaks are observed, turn off the water and call for profes sional help. While pool is filling, check the filtration equip ment for operational read iness. Follow the manu facturer's recommenda tions for oiling and clean ing required prior to putting your pool filter in- GLAVIANO'S INTERIOR'S SPECIALIZING IN KITCHENS AND VANITORIES STOCK - CUSTOM PRICED TO SELL!

Start tip filter as prescribed by the manu facturer. According to Johns- Manville, a major manu facturer of filter aids, fil ters of the diatomite type call for proper precoating of the filter elements with a filter aid that assures an efficient operation and crystal clear water. This water quality is obtained by circulating a slurry, or mixture, of diatomite and water into the filter to provide a coating about 1/16 of an inch thick on the elements. A supply of diatomite should also be placed in to the filter's body feed apparatus, if one is used. The body feed is a means of adding small amounts of diatomite at frequent intervals or continuously during the filtration cycle to separate slimes apd other dirt and prevent them from clogging the precoat layer. When a filter goes into operation in a newly-filled pool, the advantages of proper filtration can be observed in a spectacular fashion. The water, though perfectly fit for drinking, may at first be cloudy and uninviting. As a result, the first few filter cycles may be shorter than usual. As filtration progresses, the improvements in clar ity and sparkle will be amazing. Complete filtra tion of the pool's contents may take up to 24 hours, depending on its size and the filter capacity. Chlor- ination of the pool water, and the addition of other chemicals or algaecides, should be accomplished before the pool is used. Be sure your pool is prominently marked as to water depth. And then take steps to make every one, especially the young sters, aware of how deep he may go before the wat er level becomes danger ous. The simple step of taking a six-foot length of wood and marking off on it the heights indicat ing the same marking on water depth will help each child determine how far he can go. It is surprising how often even older chil dren are not aware that water four feet deep will come up to their chins. * Depending upon the fre quency with which the pool is used, the temper ature, and the efficiency of chlorination and pH control, most pool filters will require cleaning at three- to ten-day inter vals. Filter cycles can be extended by proper care of the pool. Frequent hand skim ming, if an automatic skimmer is not installed, and vacuuming will ease filter load, and careful control of algae by chem ical treatment will cut op erating expenses. Filter should be run so that the pool water is completely filtered every 18 to 24 hours. Diatomite is not expensive, and the cost of proper filtration, says Johns-Manville, will be small compared with the pleasures of swimming in clear, inviting mountain spring type water. You can build this at tractive barbecue with a minimum of effort and have a lot of fun doing it following plans just made available by Z-Brick. And it costs a lot less than masonery. The barbecue is essentially a simple plywood box built upon a sturdy inner frame. A round opening at top lets you insert any standard bar becue unit you wish, com plete with legs.
