Aquaja Diamond Line 400

The second model of the Aquaja Diamond Line series has a volume of around 300 liter. The aquarium, with dimensions 100x55x55 cm, has ultra-clear glass (front & sides).

Each aquarium is equipped with a black glass overflow box with removable combs and a covering plate. The aquarium has 1 turnable water outlet. Inside the overflow box you can find a double drainage system; the PVC50 main drainage (with the integrated PVC20 return pipe) and a PVC32 emergency drainage.

The main drainage has a precision gate valve which contrails the flow through the drainage. This can be adjusted very accurately.

Inside the furniture you will find our design sump. The sump has a special white finish. The sump has a removable filter bag holder with 2 filter bags.

The design aquarium comes with a fully pre-assembled furniture with 2 soft-closing doors.

This aquarium is also available in white.


The Aquaja Diamond Line aquariums are a series of high-quality rimless aquariums with ultra-clear glass and an overflow box out of black glass. The furniture is a fully pre-assembled aluminum frame with high-quality Perfect Gloss MDF-panels and is including a white design sump.

With each Aquaja Diamond Line model you have the possibility to order an optional lighting hood, to allow you to work with a closed system as well.

The lighting hoods are made with a glass inside-frame and are furnished with high-quality c-bond panels. The lighting hood has 2 holes on the backside and is equipped with removable covering plates (with ventilation rosters).
