AirOxi King Spider is a unique design which gives rotational / directional flow to the water.
You can choose to replace all regular AirOxi Spiders with the AirOxi King Spider, or you can add these as extra to give water movement.
If you want to get continuous water rotation, then you replace all the spiders with these. However if you want water rotation just 2-3 times a day, then you can continue using your regular aeration and add some King Spiders.
When the AirOxi King Spiders are being used, avoid using other methods of aeration otherwise the water flow will get disturbed and you will not get the desired result of brining sludge in the middle.
To calculate how many King Spiders are needed:
For 10,000 ltr tank - 2 pieces are enough to give the required water rotation. Use them for half hour 3-4 times a day to move the sludge and use regular spiders rest of the time
For 30,000 ltr tank - 2 pieces are enough to give the required water rotation. Use them for half hour 3-4 times a day to move the sludge and use regular spiders rest of the time
In case you wish to use only one type of aeration device, then replace all Spiders with King Spiders and install them on the border. King spiders will not give proper directional flow if they are not used on the border
