Salinity Testers

Salinity testers for your aquarium allow you to ensure that you are creating a balanced marine environment for your fish and coral to thrive in.

Too much or too little salt in your water can mean that the life you are keeping in your tank can suffer, and balancing it can be a difficult act considering the number of water changes you need to do over the months and years you keep your tank.

Salinity Testers examine your water's salt content, ensuring that the water in your tank and the water you top it up with is at just the right level. They come in different forms, from simple Salimeters to sophisticated refractometers.

All the products on the Swell UK range have been selected for their reliability and value-for money, and we like to keep our prices low.
