Aquarium with soft water? Endless dilemma: soft water or tap water?
October 16, 2021
Although there are many beautiful tap water aquariums on the web, the quality of tap water can vary from area to area and from city to city. You need to check the local waterworks website or measure the general tap water parameters. At a water hardness of 10-25 nk°, softening in planted aquariums is recommended.
Why soft water is good?
Learn the secret of our beautiful aquariums!
In soft water, plants can grow stress-free with proper nutrition. They develop more spectacularly, and faster and we do not find algae due to stress. Moreover, algae growth will generally be much rarer. That is why we also use only RO water in our showroom aquariums and client installations.
Things to consider when buying
Can we store RO water, and how long the process takes?
RO water production is a slow process. If we have space to store water e.g., barrel, entry-level equipment may be sufficient. If we do not have the opportunity to do so, we should not give up the benefits offered by RO water either. We need to choose a faster, more powerful machine to produce soft water directly into the aquarium for water changes.
How to use it?
The optimal temperature at water changes is essential
The RO device is connected to the cold water line. If the water is too cold during storage, we need to heat it up. A simple heater is suitable for this task. It is good to get a thermometer and measure the stored water or aquarium water after water changes. Heat your water to at least 20-22 degrees. Too cold water can cause stress to fish and trigger a negative algae growth process (e.g., hair algae).
In addition to the temperature of the water, it is also worth looking at its mineral content. A TDS meter can help you with this. If the aquarium water is below 120 ppm, use GH / KH plus. In the case of active soil, the use of GH plus is sufficient.
Minerals after water change
They help stabilize the water
No additional (KH lifting) minerals are needed if active soil is used because clay soils stabilize the water. In this case, using GH Plus is sufficient. When using sand and gravel (inert substrate), the GH / KH plus is strongly recommended. This way, we don’t have to mix tap water, and only minerals that we put into it get back into the aquarium.
Can we speed up the process?
In addition to speed, efficiency can also be improved!
Small RO Systems produce a lot of wastewater as a by-product of filtered water. In addition, RO water is produced relatively slowly. Larger multi-membrane systems work more efficiently because they produce less wastewater, and the speed can be significantly increased by adding a booster pump. An efficient system can produce 10 times as much water as the basic models in the same amount of time, with less waste.
RO System maintenance
How often do I need to change the filters?
It is suggested to replace the pre-filters every six months. Membrane replacement is usually three years. It is advisable to "flush" the membranes after use, as this can significantly extend the life expectancy of the membranes.
