How often do I need to clean the filter?
The filter should be cleaned every 4 weeks.
How do I clean the filter?
To clean the EasyCrystal filter, all you have to do is replace the filter cartridge. You can remove it from its practical clip holder quickly and easily, without even getting your hands wet. After cleaning the filter, you should always add nitrifying filter bacteria to it in order to maintain a stable biological balance. Filter bacteria are live bacteria that settle in the filter and convert nitrite (which is toxic to fish) into non-toxic nitrate. This natural degradation process is a key part of biological filtering. Never use chemical agents when cleaning the filter, otherwise you will harm the population of fish bacteria in the long term. For the same reason, we also recommend that you do not clean the filter and carry out an obligatory partial water change at the same time. This will ensure that the necessary core population of nitrifying bacteria remains in the aquarium.
Where in the aquarium should I place the filter?
The filter outlet should be positioned above the water surface. That way, the aquarium water sucked up from the tank is returned at the water surface, which ensures excellent water circulation and encourages oxygen enrichment at the water surface.
What are the advantages of an internal filter versus an external filter?
An internal filter is much simpler to install than an external one. What’s more, by placing the filter directly in the aquarium, you can easily access it, for example to clean or replace the filter medium. A further advantage of an internal filter is that, unlike an external one, you don’t need a cabinet to stow it away.
My filter is making a loud buzzing noise, what can I do/change? What could be causing it?
Check the water level. The motor unit should be completely under water.
Do I need an extra pump for the oxygen supply?
No, simply placing the filter outlet above the water level creates enough surface movement to ensure oxygen enrichment.
I just installed my filter for the first time but it won’t work. What can I do?
- Check the plug/power supply.
- Check whether the pump is fully immersed in the water.
- Check the motor/rotor for blockages caused by large dirt particles.
Can the filter also be used for turtles?
Yes, but pay attention to the volume and water depth to make sure the filter is sufficiently immersed. The motor unit of the Easy Crystal 100 filter is right at the bottom of the housing and is therefore ideal for shallow water.
Is the filter also suitable for young fish/shrimps and dwarf shrimps?
Yes, but you need to make sure that the upper part of the filter (filter opening) is at least 1 cm above the water surface. To be on the safe side, you should place a protective device on the filter inlet (e.g. coarse filter mesh or filter foam – not included with the filter).
Can a heater fit inside the filter? (or: Does the filter include a heater?)
No, the filter does not include a heater and cannot accommodate one.
Does the filter contain activated carbon?
Yes, the filter has a filter cartridge containing activated carbon. The purpose of activated carbon is to filter harmful substances or medicine residues from the water in the short term.
Do I have to keep the filter permanently switched on?
All filters should be permanently switched on so that the essential filter biology for cleaning the water can develop. The pumps are therefore designed for continuous operation and to optimise energy consumption.
How high should the water level be?
The rotor/motor housing must be under water for the Easy Crystal 100 to work properly.
Is it OK if the pump rests on the gravel?
The bottom of the filter housing, as the lowest point, should be at least 3 cm above the substrate, otherwise the suction surface and filter performance are reduced.
