Expansion module for CO2 reactors for the purpose of changing to a larger aquarium or for higher water hardness. Easy to build into the JBL Taifun diffusion reactor. Extends the diffusion path by 50 cm. Increases the CO2 supply: Fits all common CO2 systems. 5 modules of 16 mm height each. Robust Makrolon, fully decomposable, easy to clean, increases capacity by 10 °dKH or 200 l at 4dKH.

The CO2 indicator is an indispensable tool when using a CO2 system. The indicator continuously indicates the CO2 value. This allows you to adjust the CO2 system so that the correct amount of CO2 is administered. -Color indicator - Instantly visible too much or too little CO2 -Delivered with piston

Refill for the CO2 advance 95 set -Refill for the advance 95 set -Easy to change -Safe to use

The solenoid valve allows you to stop the CO2 supply at night when plants are not absorbing CO2. You can switch this valve by means of a simple timer. This solenoid valve is easy to connect to the supply hose. -Easy to install -220 V -Turnkey with plug.

For starting CO2 fertilization in an ideal way Carbon dioxide (CO2) is the plants' basic nutrient and allows setting a slightly acidic pH value preferred by many plants and fish. The easy-to-install and easy-to-use CO2 fertilization system sera CO2-Start is ideal for the widely spread and popular smaller aquariums up to about 120 liters. sera CO2-Start consists of an optically unobtrusive sera...

CO2 fertilization tablets for the CO2 diffusion reactor The sera CO2-Tabs are simply inserted into the respective shaft of the CO2 diffusion reactor. Each tablet then releases approx. 100 ml (corresponding to 2,500 bubbles) of CO2 upon contact with the aquarium water.

Optimal enrichment of the primary plant nutrient carbon dioxide: CO2 diffuser for small freshwater aquariums (20-400l). Fits all common CO2 systems: Connection to CO2 hose (4/6 mm), insert diffuser into the aquarium with suction cup holder. Even outflow and effective distribution: Special ceramic for particularly small CO2 bubbles, built-in ceramic membrane. High-quality glass design.

Processes such as CO2 supply to the water depend on the pH value and can therefore be easily determined and controlled via the pH value. The seramic pH-Controller measures the pH value of the aquarium water and controls a connected CO2 fertilization system according to the settings made. For this purpose, the device to be regulated is connected to the seramic pH-Controller via a socket, the...

Fertilizer system, completewith accessories for safe CO2 supply CO2 is the most important nutrient for aquatic plants, a balanced CO2 supply is one of the most important factors for great growth. The sera flore CO2 fertilization system allows optimal care for aquariums up to 300 liters. The high quality of the components it contains ensures safe and above all easy use. The set consists of: sera...

Simple night switching of the CO2 supply The sera CO2 solenoid valve for night switching in combination with a timer precisely controls CO2 shut-off during the night or another time. It is suitable for installation in already existing and new pH-controlled CO2 fertilization systems. A CO2 pressure reducer must be installed between the sera CO2 solenoid valve and a CO2 gas cylinder.

Powerful direct CO₂ diffuser. For economical and direct plant fertilization: CO2 diffuser for outdoor filters. Easy installation: Connection of external filter with hose. Exact dosing: Integrated bubble counter, no backflow of water due to backflow fuse. 20 % CO2 savings through particularly effective membrane. Contents: Powerful direct diffuser, ProFlora Direct. Inline diffuser. Optimal plant...

The Colombo CO2 advance set consists of a pressure cylinder containing 95 grams of CO2, a pressure regulator, a 3-in-1 diffuser and all connections. With the pressure regulator you control the amount of CO2 flowing into the diffuser. Inside the diffuser, the built-in bubble counter allows you to see how many CO2 bubbles are released in a given time. The diffuser produces very fine bubbles so...
