Air in the system and Main drain not sucking coreectly

[Chazrefere]

My pool is running like it's running on seven cylindees (instead of eight). I have a cartridge filter system and I cleaned them thoroughly with a pressure sprayer.

I put everything back together and therer still appears to be air in the system.

The water is cloudy and I have releived the air pressure from the pressure relief vave, but still I can see air bubbles in the first and second filter as well as the in-floor cleaning system.

Check for any leaks of water when filter is off.
If you are getting any drips, you are also sucking air...
