Carb L is an activated carbon specifically made for permanent and long-term use.

Extremely pure, vapour-activated and pre-washed activated carbon for efficient removal of yellowness, turbidity and harmful toxins, essential for maintaining good water quality in any aquarium. Carb L is almost entirely free of phosphate and has an extremely high capacity. Carb L is specifically made for permanent and long-term use but should be exchanged every 30 days. Suitable for freshwater and marine aquaria, cleans the water without any negative side effects.

Continous aquarium water treatment using Carb L (super pure pelletized activated carbon) plays a fundamental role in the Zeo-Light-System. Carb L is essential to the keeping of sensitive SPS and LPS corals and therefore is applied permanentely. The activated carbon treatment provides crystal clear water – phenoles, proteins, coloring substances, odor, and coral and algae toxins are removed effectively.

Dosage

1 L (500 g) per 1000 L (260 US gal lqd) aquarium water if applied in a flow-through filter unit
(flow rate max. 200 L ( (52 US gal lqd) /h).

2 L (approx. 1000 g) per 1000 Liter (260 US gal lqd) aquarium water if applied in a filter bag.

Change interval

Replace the activated carbon after 4 weeks in a fortnighly alternate routine to the zeolite change.

Preparation

Prepare new activated carbon after the following procedure:

One day prior to the carbon replacement pour hot water (tabwater) over the carbon and subsequently give the carbon a 24 h bath.
