Aquarium Filters: The Biological Foundation of Fish Health

Aquarium filters do more than make water clear—they house the beneficial bacteria that convert toxic fish waste into less harmful compounds. Understanding filter types, sizing, and the nitrogen cycle helps create stable aquatic environments where fish thrive rather than merely survive.

The Nitrogen Cycle

Why filtration truly matters:

Ammonia: Fish waste produces ammonia, which is toxic even in small amounts.

Nitrite: Beneficial bacteria convert ammonia to nitrite, still toxic but less so.

Nitrate: Other bacteria convert nitrite to nitrate, tolerable in moderate amounts.

Removal: Water changes remove accumulated nitrates.

Your filter provides surface area for these bacteria to colonize. The biological filtration is more important than mechanical water clearing.

Filter Types

Major categories of aquarium filtration:

Hang-on-Back (HOB):

• Hangs on tank rim, motor draws water up
• Easy maintenance, cartridge replacement
• The Hygger HOB filters (around $15-25) suit 10-50 gallon tanks
• Good for most beginners
• Moderate noise from waterfall return

Canister Filters:

• External cylinder with pump
• High capacity, multiple media stages
• More expensive, complex maintenance
• Best for larger tanks (50+ gallons)
• Quietest option

Sponge Filters:

• Air-driven foam block
• Gentle flow, safe for fry/shrimp
• Cheapest option
• Requires air pump
• Good supplemental or breeding tank filtration

Internal Filters:

• Submersible motor and media
• Takes tank space
• Budget option, limited capacity

Sizing Your Filter

Filter sizing involves gallons per hour (GPH) turnover:

General rule: Filter should turn tank volume 4-6 times per hour. A 20-gallon tank needs 80-120 GPH.

The Hygger 105 GPH: Rated for 10-20 gallons per this formula.

Overfiltration: Larger filters on smaller tanks isn't harmful—more biological capacity.

Underfiltration: Creates water quality problems as bacteria can't process all waste.

Media Types

What goes inside filters:

Mechanical media: Sponges, filter floss—trap particles for clear water.

Biological media: Ceramic rings, bio-balls, sponge—surface area for bacteria colonization.

Chemical media: Activated carbon, specialty resins—remove dissolved organics, medications.

Prioritization: Biological filtration most important. Mechanical keeps things tidy. Chemical optional and temporary.

HOB Filter Selection

The Hygger quiet HOB (around $15) represents entry-level features:

Flow adjustment: Allows reducing current for betta or other slow-water fish.

Prime function: Self-priming eliminates manual water filling.

Media compatibility: Uses replaceable cartridges or customizable media.

Noise level: "Quiet" marketing varies—waterfall noise inevitable.

Large Tank Considerations

The Aquarium Filter for 75-200 gallons (around $60) addresses bigger tank challenges:

Higher GPH needed: More water requires more turnover.

UV sterilization: Some models include UV to kill algae and pathogens—effective but increases cost.

Canister consideration: At this size, canister filters often make more sense than HOB.

Multiple filters: Two smaller filters provide redundancy over single large filter.

Green Water Solutions

UV filters address specific problems:

Green water: Suspended algae cloudiness, not harmful but unsightly.

UV treatment: Water passes UV light, killing algae cells.

Prevention vs cure: UV treats symptoms; excess nutrients (light, fish food) cause algae.

Runtime: UV bulbs need replacement every 6-12 months for effectiveness.

Filter Maintenance

Proper maintenance preserves biological filtration:

Never replace all media: Bacteria live in filter media. Replacing everything crashes cycle.

Rinse in tank water: Chlorinated tap water kills beneficial bacteria.

Stagger replacements: If using cartridges, run new alongside old before removing old.

Don't over-clean: Some debris is normal and healthy.

Common Mistakes

New fishkeepers often err:

Replacing cartridges on schedule: Marketing suggests monthly replacement; bacteria need established media.

Over-cleaning: Sparkling clean filters lack beneficial bacteria.

Turning off during maintenance: Hours off can harm bacteria populations in established tanks.

Undersizing: Minimum rated capacity often isn't enough for heavily stocked tanks.

Practical Recommendations

For beginners (under 30 gallons): HOB filter rated for your tank size. Hygger offers good value entry point.

For established keepers: Consider canister for larger tanks—better capacity and quieter operation.

For breeding tanks: Sponge filters provide gentle flow safe for fry.

For green water issues: UV sterilizer addresses algae, but also address root causes (light duration, feeding).

The key insight: filter shopping isn't about water clarity—it's about providing stable homes for beneficial bacteria. Choose filters for biological capacity, not just mechanical filtration, and maintain them to preserve rather than destroy bacterial colonies.
