Watermatic® Controllers

Automatically monitor and maintain the chemical balance in your pool and spa

Automatically monitor and maintain the chemical balance in your pool and spa

Watermatic controllers automatically monitor and maintain the chemical balance in swimming pools and spas.

Designed for easy installation and operation, they can be used with liquid feed pumps, granular and tablet erosion feeders, ozone generators, and salt chlorinators.

During the filtration cycle, the controller maintains sanitizer levels and pH balance by constantly measuring the Oxidation- Reduction-Potential (ORP) and pH balance of the water. If the sanitizer level (ORP) or pH falls below a predetermined set point, the controller activates the chemical feeder.

Frequently asked questions

If the chlorinator and pump are running, it is normal for a cloud of small bubbles to be produced in the cell, indicating chlorine is being produced.
Surprisingly, the issue here is not too much chlorine, as many imagine. Chloramines are formed by the bonding of chlorine with amines from sweat, urine and other sources. These chloramines make the "chlorine" odor and can also cause eye and skin irritations. Free chlorine does not smell (up to 10 ppm concentration). The remedy is to super chlorinate/shock dose. Refer to owner's manual for step by step instructions on how to shock dose.
A chlorine residual of 1 to 3 ppm is considered desirable. The solution is to super chlorinate or "shock dose" especially in hot weather. This procedure raises the chlorine residual to a very high level for a short period of time and reduces chlorine demand. You will also need to check your stabilizer (cyanuric acid) levels to ensure it is between 30-50ppm. Refer to your owner's manual for step by step instructions on how to shock dose.
To test for chlorine residual, switch on the filtration system and turn the chlorinator to maximum output. After a few hours take a water sample from the pool. Test this water with your test kit or take it to a local pool professional. A minimum chlorine residual of 1 to 3 ppm is desirable. 1. Adjust PH within the range 7.2 to 7.6. Make sure your cell is clean (clean if required). 2. Check your stabilizer (cyanuric acid) levels. Increase the setting of the chlorine output control. Adjust total alkalinity to recommended range. Test for phosphates. Adjust total hardness to recommended range. 3. Increase chlorinator to maximum output. Check salinity level and ensure it's within the recommended range. Increase the running time of the filter and chlorinator. Make sure the filter is clean and functioning properly.
If algae is present and a chlorinator is being used, algaecide can be used to remove troublesome algae. Please keep in mind that if you are also using a Nature 2 product, it is important not to use copper based algaecides.
This is caused by combined algae and bacteria growth. Scrub down affected walls and super chlorinate/shock dose using a large shock dose of liquid chlorine. Refer to owner's manual for step by step instructions.
There are a couple of causes for this. First, your pH may be incorrect; test the water and adjust the pH range from 7.2 to 7.6. Second, the Total Alkalinity may be high; test the water and adjust total alkalinity from 80 to 120 ppm. Third, the Calcium Hardness may be too high; test the water and adjust the Calcium Hardness from 150 to 400 ppm. 1. Clean the scale from the cell (refer to the maintenance section in your owner's manual for step by step instructions) and increase the running time of the filter and chlorinator. 2. Make sure the filter is clean and functioning properly.
Please refer to your Installation Manual for optimum pool water conditions, as these conditions may change depending on which product you're using.
Shocking is the same as Super Chlorinating. Shocking burns out the organic material that combines with chlorine. This frees the chlorine for sanitizing. Shocking is accomplished by raising the chlorine level quickly and dramatically. When the chlorine level is raised from 5 to 15 PPM the pool water is said to have been Super Chlorinated (shocked). NOTE: On initial startup of a pool, it is best to Super Chlorinate from an outside source, i.e., use a shock treatment available at your local pool supplier.
