FAQs

How do I prevent baby fish from being pulled into my filter?

Make an incision in the center of a coarse, open cell foam filter block and insert the siphon tube strainer into it. We recommend rinsing the block every 2 weeks to ensure proper filtration performance.

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.

What general maintenance tips do you have for this filtration series?

Do you have any tips for fixing common filtration issues?

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.
