How to Choose Aquariums
Tank Size
Choose a filter that matches your tank size. For small tanks, around 5-20 gallons, look for a filter rated for that range. Larger tanks above 20 gallons need more powerful filters.
Filtration Type
There are three main types: mechanical, chemical, and biological. Mechanical filters remove debris. Chemical ones remove impurities. Biological filters support good bacteria for fish health.
Flow Rate
The flow rate is how fast water moves through the filter. Aim for a flow rate of 4-5 times the tank volume per hour. A 20-gallon tank should have a flow rate of 80-100 gallons per hour.
Maintenance Needs
Consider how often you want to clean the filter. Some filters need monthly maintenance, while others can go longer between cleanings. Easy-to-clean options save time.
Noise Level
Look for filters that operate quietly, especially if the tank is in your living space. Check user reviews for comments on noise levels.
