ITEM DESCRIPTIONS and DESIRED VALUES |
| |
pH 7.2 . . . Maximum of 7.4 |
6.8 - 7.0 For Fibreglass or Paint |
| Only correct the pH 24 hours after the TA,(as below) is balanced. |
| Add 500g {maximum per day) of dry acid mixed in a plastic watering can, to the surface of the pool with the filter pump running. |
Check the pH the following day (a false reading may be obtained if done on the same day)Fill the large tube with pool water to the pH line
Add I drop of solution (antichlor) #4, swirl to mix.
Add 5 drops of solution (phenyl red) #2, again, swirl to mix.
Read the pH by comparing the colour in the tube against scale of colours representing pH adjacent to the tube. |
| |
AQUABRITE . . Pink |
2+ppm |
| Use the small test tube, fill to the top. |
| Add a DPD #1 tablet and shake to dissolve, then leave for 15 minutes before reading the colour against the chlorine scale ( reacts faster with warmer water at spa water temperature.) |
| Colour should be pink, not yellow or colourless. If colour is less than 2 (on the chlorine scale) then add a I Kg pack of AQUABRITE to each 50,000L of pool water. |
| |
COPPER TEST . . . Yellow |
0.6 ppm |
| This test is normally only required once a month. |
| Collect a sample of pool water in the empty tube of the Aquamatics Copper Test Kit provided. |
| Add 10 drops of copper reagent. |
| Leave for two(2) minutes before reading the colour. |
| Check the colour - must not be darker than the highest reading on the colour card in the Test Kit. |
Should the colour be darker than the highest reading on the colour card, the pool is being over-ionised and the ionic water purifier should be turned off until the copper reading drops to within the normal operating range.
Measure the copper every week until the system settles down. Generally, operate the ionic Water Purifier for I Hr per day for every 1 O,000L of water in the pool. |
| |
TOTAL ALKALINITY (TA) |
80 - 100 ppm |
| This is a measurement of bicarbonate, (TA), in parts per million (ppm) |
| Collect a sample of pool water in the larger test tube and fill to lower line marked on tube. |
Add 2 drops of blue dye marked #1, then add dropwise the clear solution marked #3, counting the number of drops it takes until the blue colour disappears.
Note: 8 - 10 drops indicates 80 to 100 ppm. |
| For every drop short of 12 drops, add 1kg of bicarbonate (maximum per day) slowly through the skimmer box. |
