not possitive but a can actualy forces water through media your quitflow just runs water over the media
a can i think would pull more solids out another think ive done is change the order your media sits in the filter also with filters its wise to have one rated for twice the size of your tank !

Gph just relates to how much gallons per hour your filter filtrates. It does not mean that your tank will get cleaner with higher gph, just that the flow will be increased. To maximize filtration you would need biological, mechanical and chemical filtration. Biological could be plants, chemical could be activated carbon and mechanical is the flow (gph) of your filter. Canisters IMO are MUCH more effective at removing debris and nutrients from your water. They do minimize O2 flow so I usually suggest an air stone if your fish start gasping for air.

If a cannister filter is providing enough filtration, but not circulation, a powerhead or circulation pump (such as koralia nano) can also supplement circulation.

Hello white...

Gallons per hour (gph) is the volume of water the filter turns over (filters) in one hour. Your filter should have a minimum gph, 6 times the volume of your tank in gallons. So, if you have a 30 gallon tank, your filter needs a gph of at least 180.

The larger the filter, the more water is filtered per hour. More isn't much better, though. Remember, a filter is only taking in toxic water and returning the same water, that's a little less toxic. Large, frequent water changes are the only way to guarantee stable water conditions for your fish and plants.
