FAQs

FAQs

I change the carbon in my filter every couple of weeks. Is this too often?

No. It’s better (and easier) to prevent odors rather than having to remove them once they’ve accumulated. Some fish are messy eaters, or are more prone to producing large amounts of waste, so prevention is key.

I found a fish stuck to the intake of my filter. Is the flow too strong?

You don’t need to be concerned about your filter being too powerful for use with healthy fish, many of whom swim in natural habitats with much stronger currents. If a fish became stuck to the intake of your filter, it’s likely that the fish was already sick. Take note that you can adjust the filter output strength to suit your particular fish species.

Why will my U Series filter not restart after maintenance?

The impeller assembly may be dirty. Detach the motor, pull out the impeller, and clean the magnet and impeller well. Also inspect the impeller for long-term wear, as it operates 24 hours/day and does require periodic replacement.

Why isn’t the spray bar or bottom outlet of my U series filter producing bubbles?

The venturi air valve only operates on the top outlet of the filter.
