Some fish, such as goldfish, produce a huge amount of waste. A filter helps to remove this waste and houses a colony of good bacteria, which remove water pollution.
But what about guppies? Do they produce a lot of waste? Do guppies need a filter?
There’s no definite answer to whether guppies need a filter – some people insist that they manage fine without one, while others would never keep guppies without a filter. Here at GFC, we recommend that you add a small filter to your guppy tank.
A sponge filter should be perfectly adequate for guppies and is better than having no filter at all, as it will certainly help keep the water a little bit cleaner.
It isn’t necessary to have a large, powerful filter for a guppy tank as, compared to goldfish for example, guppies don’t produce very much waste and won’t pollute their water quickly as long as they are kept in an appropriately sized tank.
In fact, more powerful filters can actually be dangerous for your guppies! The strong current created by the filter can drag them in to the filter or pin them against the side of the filter inlet!
Of course, whether you have a filter or not, you should do regular water changes to make sure that your guppies’ tank water doesn’t get too polluted!
