Where

 

The Aqua-DOC is simply strapped around the return line before the water enters the pool or spa. The Aqua-Doc can be installed on either PVC, copper, iron or flex pipe.


Testing

 
Check water hardness and total alkalinity for proper levels. If you do not have the proper test equipment to perform the tests, most pool equipment stores will run the tests for you. Hardness should be in the 150-250 range. Total alkalinity should be 90 ppm for plaster pools and 100 ppm for vinyl, acrylic, painted and fiberglass. If the hardness is above the 150-250 ppm range, alkalinity should be reduced with acid. This table shows the proper level for alkalinity based on the amount of hardness. For example, if the hardness is 500 ppm the alkalinity should be 70-80 ppm. This is the most important adjustment to be made to ensure the Aqua-DOC works properly. Readings higher than those recommended will still work, but readings lower than recommended may cause expensive damage to equipment.

Running the Pump

 

The recycling pump should be run continually for at least 24 to 48 hours after installing the Aqua-DOC to ensure water is fully conditioned. After the initial period, the recycling pump should be run a minimum of 2 hours a day for a spa and 6 hours for a pool application. Longer recycling periods may be necessary depending on swimmer load.


Sanitizer Level

 

Chlorine/bromine levels should be at the normal recommended levels during the first few weeks the system is claritying itself. After that, the residual may be reduced in a private pool or spa to about 1/2 of the normal recommended amount. For commercial systems, follow the health department requirements.


The Filter

 

Clean or backwash the filter after installing the Aqua-DOC. Watch filter pressure since Aqua-DOC will start to coagulate solids, minerals, algae, etc. that are in the water into large enough clumps to be filtered out. This could clog the filter and raise filter pressure to a dangerous level. Since Aqua-DOC increases the efficiency of the filter, it should be backwashed or cleaned more frequently than usual.


Scale Removal

 

Scale and calcium will start to dissolve and return to suspension in the water. This may cause a period of cloudy water for a few days. Relax and wait for the enhanced filtration of the Aqua-DOC to clarity the system.


Maintenance

 

Keeping the filter clean and maintaining the proper sanitizer (chlorine/bromine) level will ensure that the pool or spa water stays clean and sanitary with the least work.


Problems

 

If you are having any problems with your water staying clear and bright, first check the filter and the sanitizer level. Clean or backwash the filter and raise the sanitizer residual to the recommended level. If the problem persists, check the total alkalinity. If alkalinity is more that 10 ppm above the recommended range, problems can arise. If alkalinity is too high, reduce it with the application of acid. Follow your water professional's recommendations on the amount and method to apply.


Other Chemicals

 

If other chemicals are needed with the Aqua-DOC system, start with 1/2 the normal amount before adding more. In most cases, less than 1/2 the normal amount will suffice.


Water Balance

 
To properly balance your water, start by testing calcium hardness and total alkalinity.

If hardness is below 15O-250 ppm. Raise total alkalinity to 90 ppm using bicarbonate of soda. Next, raise calcium hardness using calcium chloride.

If hardness is above 250 ppm. Find the hardness reading on the index scale and read total alkalinity opposite it in the alkalinity column. Raise total alkalinity, if necessary , using bicarbonate of soda. If total alkalinity is already above the ideal reading for the corresponding hardness level, use acid to reduce alkalinity to the level opposite your hardness reading. Follow your local water professional's recommendation on the amount of acid to apply and the proper method.

Using the Aqua-DOC system, pH can be allowed to float between 7.2 to 8.2.


Tandem Series

 
Some Aqua-DOC models are designed to be installed in tandem with other units. Each Aqua-DOC unit consists of two halves which surround the pipe. Some models consist of four or six half units. These models are designed to be mounted in tandem with a spacing of 1 3/4" between each unit.

Money Back Guarantee

 

The Aqua-DOC water conditioner is guaranteed to perform as stated in our literature. Since each system is different, the product must be installed for a period of 60 days to properly solve each unique water situation. If within 60 days after the initial 30 day period the product does not perform as stated, simply return the unit in resaleable condition to your dealer for a money back refund.
