DAY TO DAY OPERATION
Four Prime rules must be observed if your unit is to give the best possible service:
1. STABILISER
The importance of pool stabiliser cannot be over – emphasised. It is essential in helping retain chlorine
in your pool. Chlorine is rapidly dissipated by sunlight and the use of stabiliser will reduce this dissipation
substantially. Without stabiliser, it may be necessary to run the Unit for up to three times as long!
Stabiliser should be added at the rate of 500 grams for every 10,000 litres of water. Stabiliser should be
maintained at a level of 30 – 50 ppm. Before adding more stabiliser, have your pool water analysed at your
pool shop to ensure that you do not add too much.
(FOR OUTDOOR POOLS ONLY, INDOOR DO NOT
REQUIRE STABILISER)
2. pH AND TOTAL ALKALINITY
A correct pH level must be maintained to prevent problems such as black spot, staining, cloudy water, etc.
An incorrect pH level can damage the pool. Correct pH levels are as follows; Fibreglass – 7.2 to 7.4
Concrete & tiled – 7.4 to 7.6 If you allow the pH level to rise to 8.0 or above, the chlorine required could be
as much as three times the normal amount.
Total Alkalinity should not be confused with pH, although the two are closely related. Total Alkalinity
determines the speed and ease of pH change. The ideal range is 80 – 150 ppm, or refer to your pool
professional.
You should use a test kit which includes a test for Total Alkalinity. Low Total Alkalinity can cause unstable
pH levels – i.e. An inability to keep the pH constant may cause staining, etching and corrosion of metals.
High Total Alkalinity will cause constantly high pH levels.
3. TDS LEVELS
WARNING: Some people recommend that you put salt directly in the skimmer
box. This is a very poor practice as it allows very high concentrations of salt

RECOMMENDED TDS LEVEL RANGE: 4,000 - 6,000ppm
WARNING: Do not add Hydrogen Peroxide to pool water or through
swimming pool hydraulic or sanitiser system. Use of Hydrogen Peroxide
will void warranty on Davey products.
Salt is NOT used up in the sanitisation process or by evaporation. It is only lost through backwashing,

pool; therefore TDS levels should be checked during these events.
Low TDS levels will destroy the coating on the Anode plates and will void all Warranty.

however, the ultimate responsibility is on the owner to ensure adequate TDS levels are maintained all year round.
4. RUNNING TIMES
These instructions cover AquaReviva for residential use only.
If you run your Sanitiser for 24 hours a day, or for long periods, the Cell life will be greatly reduced. It is important that
the correct model AquaReviva has been installed on your pool. Many models are available from Davey to cope with
small courtyard pools up to commercial applications. (Consult your local AquaReviva Dealer for more information).
Note: The AquaReviva guarantee does not apply to commercial or semi-commercial installations, i.e. where the
system runs more than an average of 8 hours per day over the year. Guarantee on commercial and semi-commercial
installations is 12 months only on both power supply and cells.
