No. Natural evaporation is between 2-5cm per week depending on wind and heat. Salt and Stabiliser do not evaporate.
Having trouble maintaining chlorine levels in your pool although you put plenty in? The most probable reason is a lack of chlorine stabiliser(cyanuric acid). In very rare instances it could be chloramines and is one of the tests routinely carried out on our visits.
About every three or four years after heavy rain we get a plague of bugs, which lasts for around 3-4 weeks. It is not caused by poor chemical balance.
Probably nothing is wrong with the pool! It is almost certainly Tropic Ear, a fungus growth caused by dampness in the ear. A Doctor can fix it very quickly, better still, teach your children to dry inside their ears as soon as they get out of the pool.
It could be that the 'PH' level is either too high or too low, only occasionally if the chlorine level is high. More often than not it is simply that the children have been swimming underwater for long periods with their eyes open. Swimming pool water is not a natural substance for the eye to be exposed to.
Three things shorten the life of your chlorinator cell -
Running the filtration for long periods on low levels of salt
Cleaning the cell in too strong a solution of cell wash
Not cleaning the cell often enough, leading to a build up of calcium
6 hours per day to filter the water clean
8 hours per day in summer - half early morning, half late afternoon
6 hours per day in winter - half early morning, half late afternoon
This should maintain clean water and produce enough chlorine
The mechanical seal needs replacing. It is important to have this simple repair done as soon as possible, or further more expensive damage will be done.
The bearings and mechanical seal need replacing, if left the pump will soon stop working altogether.
The impellor most likely needs replacing along with associated bearings and mechanical seal.
The water level is too low, it should be at least half way up the skimmer box opening, with about 2 cm (1") gap at the top. Don't forget to bleed the air out of the filter!
Either the water level is too high, drop the water level to 2 cm below skimmer opening, or the weir door is missing.
Multiply the longest point (in meters), by the widest point, by the average depth, this will give you the approximate volume in liters.
Diatomaceous Earth (DE) Filters offer the highest quality of water filtration. DE filters clean down to 3 microns, and give the best water clarity of all types of filters. DE filters have a backwash valve for ease of cleaning.
Sand filters work by filtering the water through sand, they cope best with high amounts of suntan cream and are therefore the most suitable for Resort pools. Sand filters clean down to 25 microns, and have a backwash valve for ease of cleaning.
Cartridge filters ideal for above ground pools, or where water is scarce. Cartridge filters do not have a backwash facility and are middle of the road for cleaning power, cleaning down to 15 microns.
Rosco’s Pool Service is happy to help you evaluate any quotes, we can point out the differences between them and make sure you are comparing the same thing. When using a member of SPASA to build your pool, you have the security of SPASA's "Watertight" insurance.
Salt-water chlorination makes your pool much easier to maintain, needing much less attention than a chlorine pool. Because the chlorinator is adding chlorine to your pool automatically, twice every day, there is much less chance of anything going wrong, avoiding costly clean up measures. Salt-water chlorination is less than half the cost of a chlorine pool to run. Saves time, saves money, eliminates problems!
Salt-water pools cost less than half that of a chlorine pool. Most of the chemical costs associated with a salt-water pool occur during the wet season when the pool fills with rainwater and overflows. During the dry season there is very little expenditure on chemicals. The costs depend upon the size of the pool, the severity of the wet season, and the situation of the pool.
