    Buying guide

    Getting the flow rate right makes all the difference to water clarity and fish health, so aim for a filter capable of turning over your tank's total volume at least four times per hour as a general guide, more if your tank is heavily stocked. If you're unsure exactly what that means for your setup, our aquarium filter size calculator makes it easy to work out the right output before you buy. Beyond capacity, look at what's inside: filters combining mechanical and biological media will clear debris while also breaking down harmful waste, keeping your water safe between cleans. A well-matched internal filter also creates gentle surface movement that helps oxygenate the tank, giving your fish a healthier, more natural environment with minimal ongoing effort on your part.
