SunSun / Grech MultiPro Filter 900 - internal filter

The MultiPro Filter has many unprecedented features aimed primarily at:
- providing the best water filtration
- facilitating filter operation and maintenance of the cartridges
- allowing full control over the filter's performance and the direction of water outlet
These aspects, along with the modern pump, make the filter undeniably one of the best among outstanding internal filters.
Its advantages will be appreciated by every professional looking for a new and good solution to many limitations arising from the design of ordinary internal filters. However, despite its advanced design, the filter can be used by a beginner aquarist. This is because its complex design does not complicate but facilitates operation, and moreover, it is ready to use.

Modular design. So, what is the MultiPro filter made of?
The MultiPro 900 model consists of 6 modules.
- Module 1
This is the bottom cap of the filter. Its task is to direct the flow of water in the filtration module mounted just above it.
- Modules 2, 3, and 4
These are filtration segments. Each of them has a heavily perforated basket-like design. Inside, there is a filter sponge and a bio-ceramic cartridge.
The design of these components forces the water to flow first through the sponge and then through the biological cartridge. The cleaned water from the lower module goes to the next one, bypassing the sponge. This way, it improves biological filtration.
- Module 4
This is mainly the construction element of the pump and its rotor. In this segment, there is another (this is the third) sponge.
- Module 5
The motor. That is, the water pump. This element is integrated with the outlet and flow regulation. You can read more about these elements below.

Water flow regulation.
You can adjust the water pump's performance freely using a large knob. Calibrate the power to your needs from 15% to 100% of the pump's power.

A water outlet like never before.
This subassembly contains several useful functions.
Here they are:
- set the outlet direction at an angle of over 90 degrees horizontally
- set the outlet direction at a 45-degree angle horizontally
- activate water aeration using a pipe and air valve
