Transcript of POOL TRAINING
HOW A POOL WORKS
Pool water is sucked out of the pool through the skimmer
It is pushed through a filter to take out fine particles from the water
Water is returned to the pool through the inlets
If particles are too small for the filter to catch then the water can be cloudy, and if the filter is blocked and pressure drops chemicals may not get to all parts of the pool
When you backwash a pool you reverse the water through the filter, this then takes any particles blocking the filter and washes them down the drain.
This restores pressure.
Balancing your pool water gets it into the right condition for chemical use. Poor balance usually means you spend more money trying to keep your pool looking great and usable
Correct alkalinity makes PH more stable
If PH is too high or low it is bad for people!! And chlorine does not work well
Hard water has minerals dissolved in it, soft water does not. If the water is soft it will absorb minerals and this can cause cracks in concrete pools. Too hard and you will get scale build up on the pool
Correct Stabiliser levels slow down how fast your chlorine reacts (and therefore you don't use as much). This is very important in summer when chlorine can get used very fast.
WARNING, if stabiliser gets too high chlorine stops working and you must change the water to fix it
If your pool is not treated in some way with chemicals, then algae will grow in it, as can bacteria (particularly in spa pools). You need to add chemicals to kill unwanted algae and bacteria. Chlorine is the most common method of achieving this
You need to sanitise the water with something that kills algae and any bacteria. The most common form is Chlorine.
You want to maintain 'Free Chlorine' in a good zone for swimming. This is between 1 and 5ppm depending on pool or spa
To really make sure you keep your pool healthy you add enough chlorine to get the level up to 10ppm regularly (but allow it to drop back to 5 or less before swimming again).
UNSTABILISED / STABILISED
Sunlight consumes chlorine in warmer months, stabiliser slows this down and saves you money. However use unstabilised in winter to avoid stabiliser levels getting too high
An algaecide like Clean the Green uses different chemicals to kill algae. They are particularly useful when fixing a green pool. And also good for a winter treatment instead of chlorine.
SALT WATER POOLS
A salt water pool uses a 'salt cell' to electrically release Chlorine from salt to sanitise the water.
NON - CHLORINE
For those sensitive to chlorine these two products work together very effectively instead.
Bromine works like chlorine it is common in spas, and some prefer it as there is less odour
