How powerful should my fish tank filter be?
A proper flow rate is essential for your aquarium’s filter to work its best. We generally recommend that on average, you turn over your aquarium volume four times per hour. This means that if you have a 30 gallon tank, you need a pump and filter with flow rates of around 120 gph.
What size filter does my fish tank need?
A good size filter for a 30 gallon fish tank is one with a flow rate of 120-150 GPH (gallons per hour). If your 30 gallon tank is planted you will need a filter with a flow rate of 95-120 GPH. A 30 gallon reef tank on the other hand will need a filter that has a flow rate of 150-195 GPH.
Is a 10 watt heater good for a 5-gallon tank?
On the market, there are 7.5w, 10w, 15w, 25w aquarium heaters—all indicating that they will work just fine for a tank 5 gallons and under. BEWARE! Not all low-wattage heaters are the same!

What size internal filter do I need?
The rule of thumb is that all the water in your tank should pass through the filter at least four times each hour. That makes it pretty easy to calculate what you need. When it’s borderline, always move to a higher flow rate. For example, a thirty-gallon tank requires a flow rate of at least 120 gallons per hour (gph).
