Diffuser Extended Original L – 25mm acrylic-ceramic elbow and diffuser

This CO2 diffuser suits aquarists who want a clear, durable diffuser that can be fitted to the glass edge without a visible tube. The acrylic body is transparent, so the diffuser is hard to see in the tank, and it will not crack like glass. The tube can be shaped to the tank's rim.

Why it matters

• The diffuser disc is made from ceramic fiber, which the manufacturer describes as denser and harder than a standard ceramic sinter, with smaller pores.
• The acrylic body is transparent and does not break like glass. It also houses a bubble counter.
• The tube can be bent into an elbow using heat, so the aquarist sets the glass thickness and the tube position. The set includes two spare tubes for practice.
• The set includes two large suction cups with a hole for the diffuser tube.

What it works with

The product data lists a 200 l low-tech setup alongside the manufacturer's 250–500 l range, so check the tank size before purchase. The manufacturer states that the smaller fiber-ceramic disc gives similar output to larger standard diffusers, which may help keep the diffuser less prominent in the aquascape. It is intended for CO2 systems in planted freshwater aquariums.
