Getting your new fish tank set up is easy for any level - from beginner to seasoned pro - as long as the feed water into your tank is right. Getting this right, with the right setup, is crucial for the fish to maintain a healthy and happy life.

It is best to know the water supply before you start. Found very often in municipal supply, chlorine exists to disinfect the water and make sure it is free of microbial contaminants. Fish do not like chlorine! It can damage their gills and remove beneficial nutrients. 

 

Testing meters 

Test your supply with our range of different meters. Get accurate readings on TDS (total dissolved solids) pH, salinity, and crucially for this application - chlorine.

Running a postcode analysis with a company such as Vyair can give a good indication of the quality of local water supplies.

 

Reverse Osmosis 

Reverse osmosis provides the perfect solution for aquarium water. A properly-installed RO system can balance pH and salinity, whilst removing contaminants such as chloramine, sodium, fluoride, lead, and crucially chlorine.

It is important to acclimate fish to the new RO water that will be its home. Use a pH test meter to test both the current housing water and the new RO aquarium water. Slowly add RO water whilst removing older water to bring the two into pH balance, preventing pH shock with the fish.

 

Remineralisation 

Although RO water provides a clean, chlorine-free environment for the fish to inhabit, it is important to know their needs. Do the research on your specific fish to find out their requirements with hard water. A lack of minerals can make the pH unstable, so a remineralisation stage is recommended. 

 

Marine aquatics

RO DI system is highly recommended for a saltwater tank. This eliminates the possibility of problems with the water quality whilst making the water changes necessary to find the right salinity/mineral levels. A larger RO DI system (at least 5 stages) is recommended to create a stable tank. This is a base level, and the approach should be altered based on the local water supply. In some cases, where there are high levels of ammonia or other contaminants in the water supply, it is worth starting out with a higher stage system (doubling up on resin or on carbon block stages).Despite the initial upfront costs, costs can be saved on buying in and storing water. Investing in a water filtration system pays for the peace of mind for saltwater fish, and the ease of being able to perform water changes on a clean canvas.
