Activated Carbon

Active Carbon has a plethora of tiny pores that cause organic or inorganic substances to adhere to them. Carbon in fresh form performs more effectively than carbon that has been used for a long time. If all pores are completely filled, the carbon's efficiency is reduced. Carbon eliminates various dangerous elements in your fish tank, including chlorine, copper, proteins, and carbohydrates. It also helps remove sulfa medications and antibiotics, which is why it should be eliminated while the aquarium is treated, and then replaced after the treatment is finished to remove any remaining medications. Activated carbon is also effective in eliminating water discoloration. This means that activated carbon is able to eradicate unsightly cloudy or murky tanks and make your tank appear so clear, you'll be wondering if water is there at all.

Filter Sponge

Sponge filters are great for filtration that is gentle and safe, Fish species like bettas which do not flourish in currents that are strong can have the benefit of sponges. Shrimp are another fish species that require gentle filtration, not an intake of force that could take them out. Sponge filters are also ideal for tanks in hospitals, as the fish tend to be fragile and unable to take the more powerful suction of the standard inlet of a filter.
Helpful Questions From Clients
Frequently Asked Questions
Is hiring a professional necessary to set up a saltwater aquarium?

As a general rule, a larger custom aquarium might require installation by a professional. However, a kit from our online fish store is relatively affordable and beginner friendly. That means you should have no problem setting it up yourself.

Which saltwater aquarium fish should you choose when starting out?

Consider a yellow tang fish. This popular saltwater aquarium fish does a great job of coexisting with other types of fish you’ll find in our online fish store.

How does a saltwater aquarium differ from a freshwater one?

Saltwater aquariums require a bit more maintenance and monitoring than freshwater tanks. Different fish require different levels of salinity, pH tolerances, and temperature requirements. They also require specialized pumps, filters, and other equipment that can handle salt. We can guide you through everything you need to know to set up a healthy, thriving reef tank.

Do fish in a saltwater aquarium swim in a school?

That depends on the species. However, if it’s a fish that swims in a school in the wild, they’ll do the same in an aquarium. Some fish that swim in schools include the green and blue chromis, cardinalfish, and dartfish, for example. When ordering from an online fish store, make sure you do your research on how specific fish species behave to ensure they’ll school (or at least coexist) with your current fish.

Is the effort required to maintain a saltwater aquarium worth it?

Yes! Many aquarists dream of owning thriving saltwater aquariums. You have a tiny piece of the ocean in your home, featuring magical and exotic fish that can only survive in saltwater.
