Grech MultiPro Filter 700 – internal filter

This internal filter is designed for aquarium keepers who want more control over water flow and filter maintenance than a standard internal unit offers. The MultiPro 700 is built from five separate modules, which makes it possible to adjust the pump output and the direction of the outlet to match the tank and its inhabitants.

Why it matters

• Adjustable flow: A large dial lets you set pump output anywhere from 15% to 100% of maximum, which corresponds to roughly 75–500 l/h according to the listed pump capacity.
• Two-stage biological filtration: Two perforated basket segments each contain a sponge and a bio-ceramic insert. Water passes through the sponge first and then through the biological media, and the lower segment receives water that has already been cleaned by the upper one.
• Multi-direction outlet: The outlet can be angled above 90° or at 45° horizontally, and it also includes a tube and air valve for aeration.
• Modular maintenance: The filter separates into modules, so sponges and bio-ceramic media can be reached and cleaned without dismantling the whole unit.

What it works with

The filter is intended for freshwater and aquarium setups where an internal filter fits the tank layout. Its 75–500 l/h flow range makes it suitable for adjusting circulation to the tank size and to the needs of the fish or plants. The package includes a suction-cup bracket for mounting, so it can be fixed to the tank wall.
