Sometimes the white cloud can be an air leak and what you're seeing is bubbles...and sometimes the cloud can be sand or zeo from your filter. HOwever, when I've had gasket problems and zeo being emitted, it is usually brown, not white. If it's sand, then you either have a lateral problem or possibly need to change your multiport gasket.
Try backwashing and rinsing first, then see if you can identify whether it's bubbles or filter stuff....
