Setting Up A Saltwater Hospital Tank: Step-By-Step Guide

how to build a saltwater hospital tank

Setting up a hospital tank is a great way to prevent diseases from spreading to other fish in your saltwater tank. A hospital tank is a separate aquarium used to temporarily hold ailing fish that need a quiet environment to heal. The tank should be set up to mimic the conditions in your main tank to minimise stress on the fish. It should be about 10 gallons in size and have a few plants or an overturned pot to provide hiding places for the fish. Use water and filter media from the original tank to provide beneficial bacteria and reduce stress. Treat the water with chlorine detoxifying water conditioners or RO/DI water, and use an ammonia detoxifier. Use a power filter with a low setting to provide both chemical and mechanical filtration without disturbing the fish. Monitor the fish's health and administer any treatments as required.

Quarantine new fish for at least seven days

Quarantining new fish for at least seven days is a crucial step in preventing the spread of disease and ensuring the health of your fish. Here are some detailed instructions to guide you through the process:

Firstly, it is important to set up the quarantine tank appropriately. The tank should be separate from your main display tank, preferably in a different room, to avoid cross-contamination. Use a separate set of nets and siphons for the quarantine setup, and always wash your hands after handling the quarantine tank. The tank should be kept bare of gravel or substrate to facilitate easy cleaning and prevent the build-up of harmful bacteria. Provide a few plants or decorations to give the fish some shelter, as they may want to hide while recovering. Use an in-tank thermometer to monitor and control the water temperature, and ensure the water is properly conditioned and oxygenated before adding fish.

When introducing new fish to the quarantine tank, it is important to observe their physical appearance and behaviour closely. Monitor their food intake and waste production by keeping the bottom of the tank visible. If the fish show any signs of illness, administer the appropriate medication following the manufacturer's instructions. You can use broad-spectrum treatments or specific medications depending on the ailment. It is also recommended to feed the fish high-quality food to help build up their immune systems.

The quarantine period should be at least seven days, but it can be extended for extra safety. After the quarantine period is over, perform regular water changes to gradually remove any medications. You can then introduce the new fish to your main display tank, knowing that they are healthy and disease-free. Clean and dry the quarantine tank setup for future use.

By following these instructions, you can effectively quarantine new fish and prevent the spread of illnesses to your existing fish. This process is an essential part of maintaining a healthy saltwater hospital tank and caring for your aquatic pets.

Use an EcoBio-Stone to keep water clean

Using an EcoBio-Stone is an effective way to keep the water in your saltwater hospital tank clean and clear. These stones are made from porous volcanic rock and cement blocks, infused with nutrients and beneficial bacteria designed to keep your tank healthy. The bacteria in EcoBio-Stones are viable at pH levels of 3-11 and temperatures of 50°F to 149°F, with the most effective range being 77°F to 140°F.

EcoBio-Stones work by dispersing beneficial bacteria into your tank, which multiply and speed up the nitrogen cycle, keeping the water clean and clear. They also help to eliminate odours and create a healthier environment for your fish. The stones are simple to use and can be used in both fresh and saltwater tanks.

To use an EcoBio-Stone, first, rinse it well with chlorine-free water and soak it overnight. Then, place the stone in your hospital tank near an airstone or where water flows, if possible. Depending on the size and condition of your tank, it can take between two days and three months to see results, with the typical time frame being two to four weeks.

EcoBio-Stones are available in different sizes, so you can choose one that suits the size of your hospital tank. For example, the M-size EcoBio-Stone treats tanks from 15 to 40 gallons, while the small size treats tanks from 8 to 16 gallons.

Using an EcoBio-Stone is an easy way to maintain water quality in your hospital tank and reduce the amount of routine maintenance required.

Use a sponge filter to bring beneficial bacteria

A hospital tank is a back-up tank used to quarantine sick fish and prevent the spread of disease. It should be set up to mimic the conditions in the main tank to minimise stress for the fish.

One of the most important aspects of a hospital tank is adequate filtration. Power filters with a low setting are generally recommended for hospital tanks as they provide both chemical and mechanical filtration without creating a strong current.

Sponge filters are another option for hospital tanks. To use a sponge filter, run it in your main tank first to allow it to establish beneficial bacteria. Then, when needed, bring the sponge filter into your hospital tank. This will bring over lots of beneficial bacteria to help purify the water. After the quarantine period, put the sponge filter back in your main tank.

Sponge filters are particularly useful for hospital tanks as they are easy to move between tanks and provide instant cycled media. They are also inexpensive and can be stored in your sump or display tank. However, they must be given the appropriate time to cycle and grow nitrifying bacteria.

Monitor the fish's physical appearance and behaviour

Monitoring a fish's physical appearance and behaviour is an important part of maintaining a saltwater hospital tank. Firstly, it is crucial to keep the hospital tank bare of gravel or other substrates. This is because a bare bottom setup allows for easy cleaning and close observation of the fish's waste, food intake, and physical appearance. Sick fish may exhibit unexpected behavioural changes, such as a desire to hide, so providing a few plants or an overturned pot in the tank can offer shelter and make them feel more comfortable.

When observing the fish, look out for symptoms of disease, such as changes in appearance or behaviour. These symptoms may include changes in colour, fins, or swimming patterns. If the fish is displaying symptoms of illness, refer to the manufacturer's instructions for specific medications to treat the identified disease. If the disease is unknown, follow general guidelines for treating sick fish. In most cases, medications should not be mixed, but some combinations are safe. For example, Hikari Prazi-Pro, an anti-parasitic medication, can be used in conjunction with copper to treat external parasites.

It is also important to monitor the fish's response to treatment. After administering medication, perform regular water changes to gradually remove the medication and help the fish recover. Feed the fish high-quality food, such as frozen foods, to help build up their immune systems. Continue to observe the fish's physical appearance and behaviour until they are completely healthy and disease-free. Once the fish have recovered, clean the hospital tank setup and store everything dry, ready for future use.

Clean the tank and store everything dry after use

To clean a saltwater hospital tank, you should follow a regular cleaning schedule, including daily, weekly, bi-weekly, and monthly tasks. Firstly, remove any uneaten food with a net about an hour after feeding your fish. Leftover food can decay and make the water cloudy.

Next, wipe away any salt residue that has built up on power cords or near the top of the tank with a cloth dipped in fresh water. Dry the cords and tank with a dry cloth. Check for salt residue daily, as it is easier to remove when there is less buildup.

You should also remove 25% of the water and replace it with new saltwater every month. Vacuum the gravel or substrate when you change the water to remove detritus, which can impact water chemistry. Clean the glass with a magnet cleaner every other day to prevent a buildup of dirt.

After treating sick fish, do regular water changes each week to gradually remove the medications. Once treatment is completed, clean the hospital tank setup and store everything dry. If you plan on purchasing more fish soon, you can leave everything running so it is ready for new fish.
