Seachem Tidal 75 Power Filter vs Fluval 307 Performance Canister Filter
Which should you buy? Here's the honest call, pulled from our full The Best Aquarium Filters: 4 Compared (and One to Skip) comparison.
The Seachem Tidal 75 delivers the convenience of a hang-on-back filter with capacity and skimming that rival a canister, all for a mid-range price. The Fluval 307 is the pick if you want the quietest, highest-capacity option and are willing to run a canister under the tank.
Seachem Tidal 75 Power Filter
Buy itA genuinely self-priming hang-on-back filter with a huge open media basket and a surface skimmer built in.
- Self-priming pump restarts on its own after a power outage
- Large open basket takes any media you like, no proprietary cartridges
- Built-in surface skimmer and adjustable flow
- Maintenance-reminder indicator and self-cleaning impeller
- Intake and skimmer assembly takes a little fiddling to dial in
- Flow can be strong for very small or nano tanks even at the low setting
Fluval 307 Performance Canister Filter
Buy itThe quiet, energy-sipping canister that hides the hardware and gives you the most media room of the group.
- Very quiet in owner reports thanks to the re-engineered pump
- Large stacked media baskets for heavily stocked or planted tanks
- Low power draw for a canister of its output
- Lift-lock clamps and EZ-Lift baskets make servicing tidier
- Higher upfront cost than any hang-on-back option
- Priming and hose routing add setup steps HOBs don't have
