My Fluval-G Filter cartridge needs cleaning all the time.
If your pre filter cartridge needs cleaning every day, this suggests that either the aquarium substrate is clogged with waste food and mulme or there may be some species of fish that are digging and foraging in at night causing the sediment and particles to become suspended in the water.

As all other filters have between a 5% and 30% bypass all this debris would have eventually ended up clogged in the bio-media.The G filter has a zero bypass and is working better than your previous filter,removing all suspended debris and not just re-circulating particles.

You may need to gravel clean your substrate, using a gravel cleaning syphon and cut down on your feeding for a week or so. This will allow the filter to catch up with the removal of the excess waste.Once the filter has removed the waste,the pre filter cartridge should only need cleaning once a week,the carbon replacing every 6 weeks and one tray of G-nodes every 6 months.
