i prefer a slower turnover for several reasons... primarily because slower water travel through the filter tends to give you a better single pass cleaning and isn't as hard on the cartridge pleats. most important is to remember to clean the filter(s) when the pressure has risen 5-7 psi over the clean pressure. and don't forget to degrease the cartridges occasionally to remove body oils etc...
The water speed through the filter should be low for best filtration. This means that your pump and filter need to properly sized in proportion to each other. A high power pump will not improve the clarity of the water if you're using an undersized filter with it.
A good rule of thumb is to size the pump so that you turn over the entire volume of water in the pool in 3-4 hours. Generally, you'll need the pump on 4-8 hours a day anyway, so you should get around two turns of the water per day, which is perfect. Then, use the pump rate (gallons per minute) to select the proper size filter (in gallons per minute). Using this method, you will ensure that you're getting good filtration, good water circulation, and not wasting electricity.
It all depends on what shape the pool is. Rectangle : L X W X Height Free-form pools like kidneys etc, need a lot more detailing. L plus W plus H The way you would do this is by measuring from the inside on the wall, to the opposite side, inside on the wall. Do this in both direction on the pool. Most people measure from top rail to top rail, this gives them a wrong measurement. Let's say you have a 15x30 oval, you would measure from inside to inside, on the wall to get you measurements. To determine the height of above ground pools, you will measure from the bottom track to the top of the wall. Let's say it is 52" so you would have a 15x30x52 pool. Just a little side note, not every above ground pool is exactly a perfect measurement, saying that a 15x30 might read 14'8"x30'4" but in turn it will be a 15x30 foot pool.
I doubt it. Not without someone adding sanitizer (chlorine) on a regular basis. An alternative would be to add a Saline System, and leave the equipment operate for a few hours per day on the Timer. The saline system will produce all the sanitizer your pool needs, automatically, from a mild level of salt dissolved in the pool water. You would need an automatic topup (fill) device as well to counter evaporation.
We built a deck on one end, about 10x10x(the height of the pool), with cement pavers under it making a floor for storage underneath it. Then around the pool (15x30) we put double landscaping fabric about 3ft wide, covered it with decorative gravel about 3" thick. Garden edging keeps the grass out, and the gravel in. We use large potted plants, small potted trees, and other decorative items, setting them in the gravel around the pool. Do not put plants and flowers directly into the ground, the roots can get under your pool and cause damage to the sides of the pool and the liner.
Depending on how much water you are losing there are a few ways first one is to let the water go down on its own until it stops dropping then your leak should be somewhere within 50-100mm of the waterlinesecondly if you empty the pool then get under the liner and move about the sun will shine through the hole then you can repair it never get under the liner on your own as you can become disorientated quite easily.
There is a component of some brands of chlorine that can cause a black coating to come over the bottom of fiberglass pools. To remove it I recommend several bottles (3-5) of Regal Stain Remover (or any comprable brand). Let the stain remover set for an hour before scrubbing the black off. If this doesn't work, it's always a good idea to contact your local pool professional. In Dallas, TX Pure Pools is your best bet. Good luck.
The size pump required is directly related to the type of filter you have. Every filter has a minimum and maximum flow rating (gallons per minute). The pump must perform within this range for the filter to be effective. Oversizing the pumps output to the filters rated capacity is a common problem that reduces the filters performance and wastes electricity and dollars. Find the maximum GPM your filter can handle. Target your pump to be slightly less than that and you should find the performance satisfactory. Pool & Spa
A 15 by 30 foot swimming pool can be any depth. As a constructor of gunite or concrete pools I could make any size of pool any depth from 6 inches to 10 feet or more. The size of a pool has no direct effect on the depth. We did pools for exercising horses that were 10 feet deep for the entire pool. A pool of any size for normal use will have a shallow end, usually 2 and 1/2 to 3 feet in depth and will graduate to 6 feet for swimming or 8 or more feet in depth for diving. With fiberglass or vinyl liner pools the depths are established by the manufacturer and you will have to choose from the sizes offered what will best suit your needs. I believe some of the manufacturers may make custom sizes per the purchasers request, but the price will be significantly higher for a special order.
Water circulation in indoor pools is at least as demanding as with outdoor pools, if not more so. Run your filter regularly and make sure you turn-over the total pool volume at least once per day. (To calculate this you need to know how many gallons per hour your pump is pumping). A general rule of thumb - run the filter at least 6 hours per day, say 8 hours if the pool is being used frequently. Chlorination is also very important. Keep the level up and you must still shock' the pool occasionally. If you are having chlorine-odor problems, look at converting to the salt system as this will eliminate any odors and the need to 'shock'. Check out http://salinepoolsystems.com. My 25x45 8ft. deep indoor pool costs less than a 1/4 of my daughters 15x30 outdoor pool to maintain. The demand for chemicals and filtration is completely dependent upon its environment. Also since chlorine is chlorine, salt systems do not eliminate odors or need to shock. They are as susceptible to chloramines, which is what you smell, as any other chlorinated pool. Salt systems are one of the biggest ripoffs to the pool owning public and in fact a fairly recent article in THEE major pool industry magazine interviewed several pool professionals who have taken them off their own pools and now require their customers to sign a hold harmless waiver on the units they install.
57-60 ceiling tiles measuring 2'x4 would cover a 15'x30' ceiling. For the least amount of trimming, place 4 tiles at 4' (trimming 1') for a total of 15'. For the 30' side, it would take 15 tiles at 2' each for a total of 30'. 4 tiles wide x 15 tiles long = a total of 60 tiles. To use the minimum number of tiles, one could run the tiles the opposite direction, although this would involve more trimming. In this case, place 8 tiles at 4' (trimming 2' total) for a total of 30'. For the 15' side, place 8 tiles at 2' (trimming 1' total) for a total of 15'. If the cuts were precise, the end tiles (cut in half) could each be figured as 1/2, for a total of 57 pieces with no waste/scrap. A total of 64 tiles would be an ample amount to cover any miscuts, in most situations.
