ONLY IF THE CALCIUM DEPOSIT CANNOT BE REMOVED
WITH FINGERS etc.
With the cell assembled and completely removed from the pipe work, place the cell upside down into a
bucket and follow the directions below for cleaning the cell with a DILUTE solution of acid.
IN A PLASTIC OR GLASS CONTAINER, dilute one part Hydrochloric (muriatic) (Pool) Acid with
ten parts of tap water (Hot Tap Water is more efficient)
WHEN MIXING, ADD ACID TO WATER, NOT WATER TO ACID
and
DO NOT MIX ACID AND WATER IN THE CELL
Do not immerse the cell electrodes in a strong acid solution, as it may shorten the cell life and damage the
electrodes.
Pour the dilute acid mixture into the cell.
When the effervescing stops inspect the cell and if still calcified repeat the process.
Rinse cell with water and insert into the pipe work when finished.
FOR SOFT DEPOSITS - Try rubbing the deposit off with your fingers or Hosing out the Cell with a
strong jet of Water. This will usually clean the cell sufficiently and cell cleaning with acid may be
avoided.
To keep the Cell deposits SOFT add 3 - 10 Kg of Magnesium Sulphate (Epsom Salts) to the pool water
every 6 Months.
Or if the Calcium is hard and frequent:
Add 25 kg of Magnesium Sulphate (Epsom salts) to the water every 12 months.
This will soften any deposits that form making them soft and slushy. It will also make the cell far easier
to clean (usually just with a rag)
Also try putting a cake of PURE soap (no additives) in the Skimmer box. You will notice the calcium
deposits become soft and slushy.
On Completion and before switching the pool system back on return all
valves back to their original positions
You may now switch the system back on checking for any leaks before leaving the system to run
automatically.
Remember in the warmer weather the system will need to operate much longer than in the winter
time –Depending on pool size and bather volume.
Remember the pool system should always be running when the pool is being used, normal filtration
times are simply to maintain the water ready for use
Always ensure your pool water is in balance, ph should be between 7.2 & 7.6 For Example a higher pH
will make the Chlorine less effective. pH 8.6 = Chlorine only 10% - pH 7.2 = 70% effective
An Auto-pH system makes the most economical use of pH minus and maintains the pool
far better than possible doing it ourselves
Use chlorine stabiliser especially during the hot weather –if you cannot easily obtain this contact
WATERMAID EUROPE S.L. we normally have this in stock –you should have approximately 50ppm.
With all methods of maintaining swimming pools it is recommended to ‘Shock’ the pool every month,
especially during hot weather.
Run the pool system for 24 hours with the Watermaid at 100%.
Algae breed during daylight particularly when it is hot and sunny –to kill algae and help prevent
occurrence of algae –Pool systems should be run mostly after the sun has gone down, this will kill the
algae and prevent them from breeding the next day.
Always operate your pool system when the pool is being used as this is when most contamination occurs.
