If you don’t own fish then you can probably just ignore this article and move on with the rest of your day. Unless you’re really keen on reading about water filtering systems, that is. For those of you who do own fish though, is your aquarium filter enough? Is it doing enough to keep the water clean and free of impurities, toxins, waste and microbial matter? Well, the answer probably depends on a few things, like the size of your aquarium, the total volume of water to be filtered and the number of fish living in the water. Essentially though, if the water always looks dirty, it’s not getting cleaned thoroughly enough.
If that’s the case, replacing your current water filter is probably a good idea. But what should you use to replace it? You could go with another filter of the same type if you’ve found a brand and size that steadily does the job for you. If you know your current choice just isn’t doing enough to keep your aquarium clean though, you might want to upgrade to something bigger, or maybe something that’s simply better made. Not all filters are created equal, though if you’re using a small-scale aquarium that might just seem to be the case.
I’m talking about canister filters. They’re pretty sizeable on average and usually meant for larger water tanks and aquariums, but they’re pretty popular because of how well they work, and smaller versions are available for home use if you’re willing to go looking for them. You can read more about them if you like, but they are at their heart the same as any other liquid filter; water with grit passes through, the grit stays and clean water keeps moving. The fact these filters use ceramics instead of lesser quality or organic materials means they don’t harbor infections or bacterial growth like other filters.
Because they’re made from porcelain but at more of an industrial grade, canister filters are unfortunately very fragile. They’ve been known to break if jarred too hard, and they won’t just get a little rip in one spot and keep working like other filters would; they shatter pretty nicely, actually. You can read more about the pros and cons at that Canister Filter Guide website, but I’ve already outlined the major differences, perks and bad points about them here. Getting back to the question I first asked then, is your aquarium filter enough?
If it is, then you’re in good shape. Even if it isn’t though, you don’t necessarily need to buy some big, bulky filter, or a bigger tank to accommodate it. You could always split your single aquarium up into two smaller ones and divvy up the contents – fish, water, furniture, rocks – evenly between the two separate tanks. This would significantly reduce the burden on each of the two individual water filters, perhaps to the point where both could operate normally and the water quality would improve. Considering the costs of more filters, tanks and supplies though, the best option isn’t immediately clear here.
