Freshwater - Water
The bottom is now ready, and the decoration in place. Time to add water! Fill the aquarium to approximately 2/3 of the total height. While you do this, place a plate on the bottom and allow the water to flow onto the plate. After all, you don’t want the nutrient substrate to get rinsed away. Use water that is already at the right temperature. For a community aquarium, this is between 22ºC (72ºF) and 24ºC (75ºF). Do not fill the aquarium until the plants have been placed. After the aquarium has been filled, you may also place the heater. Set the thermometer to 24ºC (75ºF). With the HS aqua Thermometers, you can control the temperature of the water. Especially during the first days that your aquarium is active, it is a good idea to do this regularly. Using the suction cup, affix the thermometer to the glass.
Making the water suitable for fish
Tap water can contain chlorine and heavy metals. These substances are harmful to the health of the fish. To make your tap water suitable for tropical fish, add HS aqua Procell to the water. HS aqua Procell protects fishes’ sensitive slime layer and this is extremely important, especially for new fish in the aquarium! If you are setting up a goldfish aquarium, we recommend first treating the water with HS aqua Gold Protect. After treating the water with HS aqua Procell or HS aqua Gold Protect, do not add anything else to the water for at least one day. After that, start the filter with HS aqua Bacto. HS aqua Bacto contains natural bacteria that purify the water, breaking down waste produced by fish and plants.
