## Description

sera Flore Carbon-dioxide Aktiv Reactor : desertcart.co.uk: Pet Supplies

Review: Great value and well designed. - Installed on outflow of working pump but not used yet as CO2 delivery not set up. Looks like it will do a great job at a very reasonable price.
Review: terrible build quality - These are honestly terribly made using cheap materials. i haven't broke mine, but i can see how so many people have. the co2 connection is ridiculous, one little knock and it will break, leaving lank water draining out to the level of your inlet pipe. when you get it installed and online the impellers don't turn without serious modification. a quick google is all it takes to establish how you can make this device work correctly, by simply "cutting bits out with a Stanly knife" or "shaving this and that". the point is...... Why??? if you think it would be nice not to have bubbles all over your tank, think again, the pearling from you plants (you may not have noticed due to the normal co2 bubbles) will make you realize you have wasted your money chasing the dream of no bubbles. do yourself a favor and by an inline diffuser. Edit- this product does what it should! I feel a bit bad due to my honest review. It does provide a way of dissolving co2 into your tank without “adding” bubbles.... it is almost silent in operation when you manage to prime it correctly! So long as you don’t try to pull off the co2 tube you prob won’t break anything. It’s hard to install because the tubing from external filters (fluval being the exception) are really not that maluable, so getting it connected is an absolute mare! (Not really a fault of the unit itself) there is the possibility of massive improvements, but they would make it cost limiting. If your patient and thorough, it’s honestly a good bit of kit

### ⭐⭐⭐⭐⭐ Easy to set up and works very well
*by G***Y on 20 May 2022*

This has been installed for 4 months and still going strong. As it dissolves nearly all the CO2, there are no small bubbles in the tank. My Co2 monitor has stayed a health dark green.
