sera flore CO2 active reactor

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.

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

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.

Co2 inlet port snapped off. Fortunately we were in the room and noticed the water level had dropped. Nothing had moved or changed and it wasn't under any stress. Just brittle plastic. If we hadn't been in the room it would have flooded a 350L tank to the external filter inlet..... a lot of water.

Ok but very delicate. The first one had to be returned as the nipple for the co2 input broke off. No tiny bubbles in the take so dissolution rate is great.

Really struggling with this... it seems to have slowed down the flow of my filter I use the tetratec 1200 for 240ltr aquarium.. I switched to this from an in-line diffuser as I didn’t like the mist of bubbles that came out of the spray bar.. however this one just seems to gather gas at the top then the propeller stops!!! It’s getting me really frustrated... I’m going to slow down the co2 it’s currently getting about 8bps maybe this is too much... I may update this review if things improve.. UPDATE tried moving the reactor closer to filter to try and get more flow as the propeller just keeps stopping and my co2 levels have dropped considerably since swapping to this from my in-line diffuser.. I am giving up and going back to my diffuser, I’ve missed the return window as I’ve faffed on with it for that long... so gonna have to try to sell it.. I’ve read reviews and watched you tube videos on it and most people seem to rate this very high but I just couldn’t get along with it at all...

Very good quality! A little awkward to fit and not all supplied fittings fitted correctly,so some improvising required! But all in all,very impressed!

Works great on a fluval 206, no lower.

Sehr guter Artikel, klare Kaufempfehlung!!!! Der co2 Reaktor ist jetzt seit ein paar Wochen in betrieb und ich kann sagen :ich bin sehr zufrieden: Er ist leise, sieht gut aus,und löst das co2 vollständigt im wasser auf (kein Nebel im Becken) PS. wenn Sie die Filterschläuche am Reaktor befestigen , benutzen Sie Schlauchschellen , Sicherheit geht vor.

Superbe bonne qualité et vraiment très efficace pour répandre le co2 dans l'aquarium avec un minimum de perte. Fini pour moi les petits diffuseurs en céramique!

Je cherchais à supprimer mon diffuseur co2 pour ne plus avoir le nuage de bulles. De ce côté c'est parfait. Par contre il y a quelques points gênants : . Le type de fixation et la torsion des tuyaux créées des vibrations audibles. (Nécessite de rajouter une mousse sous le support) . Fonctionne avec un léger bruit de "cascade", faut aimer. Non gênant au salon. . A manipuler avec précaution. L'entrée co2 semble très fragile . Fixation des tuyaux ne donne pas confiance. J'ai rajouté des colliers inox. Malgré tout, satisfait par rapport au diffuseur co2. Consommation identique après plusieurs semaines de test.

Funziona alla grande per il mio acquario da 200 litri, prima non riuscivo mai ad avere la giusta quantità di co2 in vasca oggi con questo ho risolto e le piante ringraziano

This is by far the best way to inject co2 into your planted tank and second is not even close. I had my presurized co2 going to my HOB filter originally. I got a Fluval 206 dedicated for just co2. I removed all the media from the 206 including foam. Hooked this reactor to the out. Placed the out nozzle of the filter directly behind my Fluval FX4 to get the best distribution. As soon as I hooked it up my plants immediately started pearling. This reactor is truly amazing and the best investment I have done for my planted tank. All the other diffuses/atomizers do not even come close to how well this distributes the co2. Instead of tapping into your existing filter just get a 206 for co2 only like I did. It works wonders. My plants are truly thanking me.
