6 Tips to Convert a Freshwater into a Saltwater Fish Tank

You will need to collect some necessary things which will help you change a tropical tank into a marine tank easily. Have a look at a few tips for the converting process:
1. Collect an Aquarium
Obviously, if you are converting a freshwater tank into a saltwater tank, then you must have an aquarium. So, no need to buy any new aquarium for that process. It really doesn’t matter, whether it is a glass or an acrylic aquarium. Moreover, the size also doesn’t matter. The thing you need to remember is the quantity. You can keep much freshwater fish together, but you cannot keep many saltwater fish together in a tank.
2. Change the Substrate of the Tank
You may have observed that the substrate for the freshwater tank and the saltwater tank is totally different because the requirements of the tropical fish and marine fish are not same.
The freshwater tank is adorned with fine gravel or small rocks, but if you want to change the tank into a marine tank, then add sand, crushed coral and reefs as the substrate of a saltwater tank.
3. Add Pumps and Powerheads in the Tank
Like the water of the sea, you need to bring a wavy effect in the water of a marine tank to bring a natural feel. So, install a pump or a powerhead in the tank to create the wave in the tank just like the sea.
4. Change the Decoration of the Tank
When we talk about the decoration of the fish tank, remember we have to change the items of the tank. In a freshwater tank, live plants, caves, and rocks are only needed as a decoration. But in a saltwater tank, you need to put some corals, sand dunes, reef works, small caves and oysters which will create a marine environment in the fish tank.
5. Check the Temperature of the Water
The water temperature, pH level, hardness, mineral level and alkalinity of the freshwater and saltwater tank are totally different. These things also affect the health of your pet fish. So, never ignore this factor while converting a freshwater aquarium into a saltwater aquarium. You can add a heater in the tank if you need to make the water of the tank warm.
6. Add a Good Filtration in the Tank
The saltwater species need a better-quality filtration system in their tank in comparison to the freshwater species. So, it is better to install a canister filter in a saltwater aquarium.
Definitely, you would require some time to convert a freshwater tank into a saltwater aquarium but the aforesaid ideas are the simplest and inexpensive ways for the process of converting a tropical environment in a marine ambiance.
