Organic pool drain cleaner
A CO2 gun can be used to clear the main drain without emptying the pool, but only by a professional. The CO2 gun is placed in the water, pressure is applied and the CO2 forces the clog out of the drain.
Your swimming pool's main drain requires regular maintenance. Although the rest of the pool's parts, such as the filter, may seem to be working just fine, the drain is always at risk of getting clogged. Because it is located at the bottom of the center of the pool, it can easily become clogged by debris that sinks to the bottom of the pool.

To prevent clogs from occurring in the first place, regularly remove debris from the top of the pool with the skimmer. By getting the floating debris out of the pool, you prevent it from eventually falling to the bottom. Place all debris in a bucket for easy disposal.
Remove the pool drain plugs and let it drain. This is the easiest way to clean out the drain.
Unscrew the drain cover and place the pool plunger over the drain. Push down on the plunger, then lift up. Repeat this several times to force the clog up and out of the drain.
Pour the organic pool drain cleaner into the drain. This will help break up any particles and debris stuck in the drain that have not been removed with the plunger.
Place the drain cover back on the drain and refill the pool.
