Frequently Asked Questions
How often should I clean the filter media?
You should rinse your sponges in discarded tank water about once a month. Never use tap water, as the chlorine will kill the beneficial bacteria colonies you worked hard to build. Replace chemical media every four to six weeks. If you notice the water flow slowing down significantly, that is a clear sign your mechanical sponges are clogged and need a quick rinse.
Do I need to turn the filter off when I feed the fish?
You do not need to shut down the filter during feeding. Most fish will consume their meal before the current carries it into the intake tube. If you notice food getting sucked up immediately, you can use a pre-filter sponge on the intake. This protects the filter from debris while keeping the food accessible to your fish.
Will a bigger filter hurt my fish?
Excess filtration is almost always a benefit. A higher capacity unit provides more surface area for bacteria, which creates a safer environment for your livestock. The only time a filter is too big is if the water current is so violent that your fish cannot swim properly. Most modern filters include a flow valve to help you dial back the power if needed.
Why is my filter making a rattling sound?
A rattling noise usually indicates that air is trapped inside the impeller chamber. Try gently tilting the filter to release any air bubbles. If the noise persists, check the impeller for trapped debris or sand. Sometimes the small magnetic part simply needs a quick cleaning to return to its silent operation.
What is the difference between a canister and a hang-on-back filter?
A hang-on-back filter hangs off the rim and is easy to set up for smaller tanks. It is convenient but takes up space inside the aquarium for the intake tube. A canister filter sits underneath the tank and offers greater volume for biological media. It is the preferred choice for larger setups or tanks with messy inhabitants like goldfish or cichlids.
