FAQ

What is filter flow rate?

Filter flow rate (GPH or LPH) is how much water the filter processes per hour. A general rule is 4-10 times the tank volume per hour. For example, a 50-gallon tank needs 200-500 GPH filtration.

How does stocking level affect filtration?

Heavily stocked tanks need more filtration (8-10x tank volume/hour) because fish produce more waste. Lightly stocked tanks need less (4-6x). Planted tanks may need less filtration due to plant nutrient uptake.

Is the filter calculator accurate?

This calculator uses standard guidelines for filter sizing. Actual needs depend on fish species, feeding amount, and tank maintenance. For precise sizing, consult an aquarium specialist.

What types of filtration are there?

Main types are mechanical (removes particles), biological (converts waste), and chemical (removes dissolved substances). Most filters combine all three. Choose based on your tank type and fish species.

How often should I clean the filter?

Clean mechanical filter media every 1-2 weeks. Rinse in old tank water to preserve beneficial bacteria. Replace chemical media monthly. Never clean biological media with tap water. Follow manufacturer instructions.
