Description

If you've been trying to get a luscious green aquascape in your aquarium but haven't managed to successfully get your plants to thrive or stay green, then you may need to add a co2 glass reactor to your tank. Placing the co2 reactor in a place where there is a nice flow of current can ensure that the tiny bubbles will be distributed evenly around your tank. Just remember, the right balance of light, nutrients and Co2 is what will help your aquarium plants grow centimetres at a time and stay green and healthy.

Rhinox co2 diffuser is suitable for tanks below 20 US gallons (76 litres). The atomic pores on the ceramic disc will break down Co2 into tiny streams of bubbles. It is compatible with pressurized Co2 tanks and DIY yeast bottle. Some people may find that it works better with a co2 tank that provides slightly more pressure for even distribution.

Usage

The ceramic disc, and the suction cup MUST be soaked in water for at least 30 minutes before use.

Always wet the glass tubing before inserting the silicon or rubber tubing (sold separately) to avoid damaging glasswares. If the bubbles are not distributed evenly, soak the diffuser in bleach (50% bleach + 50% water) for a few hours to clear the ceramic plate.
