TIPS TO POOL OWNERS

Test your pool at least twice weekly. Keep your pH between 7.4 - 7.6, your Total Alkalinity at approximately 100ppm andfree Chlorine reading between 2.O - 4.Oppm. Replace your test kit reagents every 12 months as reagents can 'go off' therefore effecting test readings.
Use a decent water testing kit - remember the test kit will give you the opportunity of looking after your water balance accurately and this will save you time and money. In our opinion all 'Mickey Mouse' units should be deposited in the nearest dust bin.
Store your chemical compounds in a dry safe area away from children and from filter housing. Corrosive fumes given off by compounds will corrode metal fittings and damage electrical parts.
Apply Chlorine at evening time in accordance with packing instructions. Do not add Chlorine Tablets to pool floor particularly in liner pools - staining will occur and always dissolve granules fully before administering to pool- DO NOT administer granules through the Skimmer units.
DO NOT mix chemicals this could result in an explosion or even fire.
Sand Filter bed should be checked every 2/3 year and replaced if necessary, if not accumulative waste can build up and impede any filtration process. Pool owners with metal filter drums should check the condition of the sacrificial anode yearly. This anode attracts the rust action in the system and not replaced will allow the filter walls to rust through.
Pads and candles in earth filters should be taken out and cleaned with a filter cleaner every 2 months whilst cartridge filter elements should be cleaned regularly. Remove elements at the end of pool season, clean and store in the dry.
Scrape off and clean the rust build up around the lid and top of metal pool pump 'Strainer Pot' chamber Then smear with a coat of vaseline. This prevents air being drawn in causing air locks and the inability to prime. Check both pump strainer basket and skimmer baskets for collective debris twice weekly.
Should you winterise your pool make sure the Filer, Boiler and Pump unit have been drained adequately to prevent frost damage. With metal pumps, to prevent your pump impellor from jamming, switch your pump motor on for a couple of seconds every month.
Make sure you add adequate chemicals to the pool to keep it clear for the winter period. Use a winter cover to keep the pool clean and to act as a protective barrier.
Cut down heat loss by using a heat retention pool cover. Do not however, leave a floating cover on or over the winter period. They can shrink and the Chlorine in the water can damage the material.
Check all maintenance equipment from time to time for possible damage and replace if necessary particularly in the case of a liner pool. Damage is expense.
Finding a leak in a liner pool:-
1. Check out for small tears, rips, damaged seams.
2. Check level of water, with filter pump off, in relationship to inlets, returns, skimmers and light fittings. If level is below check hydrostatic valve seating in main drain.
3. If liner was laid on sand bed and over 5 years old check under liner for multiple small holes.
4. If no damage in above fittings, pressure test flow lines.
LEAK SEALING COMPOUNDS ARE AVAILABLE.

HOW TO BEAT THE BRITISH WEATHER
|
As you look out of your window at this indifferent British Summer and your deserted Swimming Pool, you must wish there was something you could do so that you and your family could enjoy a swim.
Well there is, don't let the weather dictate your leisure , you can do something about it. The answer is to install a Pool Dome and here are ten reasons why you should act now.
1 .ECONOMICS The Pool Dome is still the most economic way to enclose your Swimming Pool.
2.YOU DECIDE WHEN YOU SWIM Don't allow the weather to dictate when you can use your Swimming Pool.
3.ADDED SAFETY Small children and family pets can be excluded from the pool water when not supervised.
4.PARTY TIME Children's parties and evening get togethers with friends around the pool need not be cancelled when the weather turns nasty.
5.EASIER POOL CLEANING Airborne debris, leaves etc., will no longer be a problem.
6.LESS CHEMICALS Less debris in the water means lower chemical bills.
7.lower energy bills solar heat gain will mean almost no energy costs from May to September and low cost beyond to the Autumn.
8.EASE OF REMOVAL The Pool Dome is a two man job to remove and re-install.
9.VARIETY OF COLOURS Clear, Sky Blue, Bronze and reinforced clear are available. Select the one to suit your garden.
10.ALL THE YEAR ROUND SWIMMING Many people do swim all the year round in their Pool Dome's.
So there you have it, ten reasons to buy a Pool Dome now and get three or more months swimming this year.
Contact us NOW and you will soon be back enjoying your Swimming Pool - in spite of the weather!

POOL HEATING COSTS
|
We are often asked, in fact we are asked by every customer, quote "How much will it cost to heat my pool?", my reply to this question is always the same , "How long is a piece of string". It is very difficult, if not impossible to answer this question truthfully and accurately. It all depends on our 'Weather' for starters. A difference in our temperature of only 1°C will make a difference in nearly 10% costs.
The effects of wind exposure and how long a cover is left off can be enormous.
We at C.J. Pools, build our pools with every aspect of heat conservation taken into account. With this in mind we have put the following information together in an attempt to throw a little light on the subject. We trust you will find it both interesting and informative.
Heat losses from a pool consist of:
CONDUCTION LOSSES - into the ground and into the atmosphere
CONVECTION LOSSES - into the atmosphere via air movement across the surface, and
EVAPORATION LOSSES - into the atmosphere as a result of the latent heat of vaporisation of water.
As a rough rule of thumb they break down as:
- 10% Conduction Losses
- 20% Convection Losses
- 70% Evaporation Losses
Conduction losses can be limited by lagging of pool and pipwork.
Convection losses can be reduced by windbreaks, heat retention covers etc.
Evaporation losses can be reduced by covers, floating or rigid.
Obviously a 50% reduction in any of these makes most difference with evaporation losses - conversely a lot of money spent on lagging pool and pipework is wasted.
The overall heat losses are higher from a concrete pool, compared to a liner pool especially if the liner has a foam insulation fitted to the walls and floor. However, the surface area is the critical factor.
The following figures are based on 2 hours uncovered and 22 hours covered per day plus average day/night temperatures.
