How To Choose The Best Filter For 75-Gallon Saltwater Tank?

Kinds of Filters

Freshwater and saltwater are not the same, so it’s important to pick the right type of filter that will help your saltwater tank.

• Chemical filters: these filters use regular or activated charcoal that eliminates dissolved impurities from the tank. They will help remove all toxins in the water. But you shouldn’t use this type of filter if your tank is medicated.
• Biological filters: this is a great type for saltwater tanks. These filters let beneficial bacteria thrive that will take in unwanted substances in the water. Live rock, which is colonized by beneficial bacteria, is the most popular kind of biological filter.
• Sump filters: this is the best type for a saltwater tank. It often consists of a filter sponge, a protein skimmer, a filter sock, and substrate reactors. It sucks water in, filters the water, and pumps it back into the aquarium. But it cost the most and needs additional equipment and plumbing.
• Canister filters: you can use this type alone or with other types of filter, out it inside or under the tank. However, it needs frequent cleaning.
• Fluidized bed filters: it’s a simple type of filter that uses sand as the filtration medium. The sand doesn’t retain waste thanks to elevated water circulation. It’s a highly efficient filter but takes a while to mature.

Filter Media

Each filter may come with a different filter media, so the choice is dependent on your preference. For a saltwater tank, you can choose bio-filters, ceramic rings, or carbon among other media.

Flow Rate

Keep in mind that the recommended flow rate for a tank is at least 4 times the tank’s capacity or higher. So, for a 75-gallon tank, you need a flow rate of at least 300 GPH (gallons per hour). But if you can find a higher rate, it will be better.

Ease of Maintenance

If you have a lot of free time, high maintenance filters may not be a problem. But if you are busy, you should get a filter that takes weeks before it needs cleaning or filter media replacement.
