Using tap water & topping up

Water changes are a key part of your aquarium care and will help maintain good water quality for the health of all your aquatic life.

Once a month you should carry out a 25% water change (drain off a quarter of the aquariums water volume), clean your filter and do a general clean-up of the fish tank.

There may be other times that you also need to do a water change such as; starting your new aquarium (we recommend you do more frequent, smaller water changes for the first 8 weeks), after testing the water quality (see test kit instructions manual for recommendations) or if you need to treat the water with fish medication.

Essentially, a water change is removing a percentage of the aquarium water and replacing it with fresh water (treated with Tapsafe). Doing this removes waste and dirt, dilutes any build-up of toxic elements and increases oxygen levels in the water – all great for aquarium life.

The video below runs you through the process of a water change to make sure you get the job done efficiently: 

Doing the water change:


Start by testing your aquarium water for Ammonia, Nitrate, Nitrite and the pH level using an aquarium water test kit.

Follow the instructions on the testing kit and make sure to keep a record of your results.

By testing your water at this point, you can address any issues you may have as part of the water change and you have a record to come back to when you test in the future.
