Hi, thank you for the review. What’s the BPS and filter flow rate for the reactor on the 80G? Does gas build up at the top of the reactor after some time into CO2 injection? Thanks.

If you don’t use cold water, the heated tubing can be put on with ease.

using metal on a CO2 reactor – – – -Not a good idea! CO2 will corrode metal…quickly! There are pvc slip on fittings available. Besides, why would you use metal of any kind – especially a garden hose fitting in your fresh water aquarium? EVEN “Run of the mill” Stainless Steel fittings are not a good idea… METAL of ANY Kind should never be used in an aquarium!

is it quiet?

Don’t you use a bubble counter?

I actually had to remove the propeller and give it a little sanding to make it spin better. And i over tighten the bottom cap of the reactor and cracked it .

quick question is this noisy? as you said its not quality and i fear the mechanism will degrade fast

Why would you silicone the bottom on the reactor? How will you clean it if you need to? Just use pipe thread tape.

What would you use on a 300 gallon tank?

i subbed great work !

quick question and somewhat off topic…what kind if lights are on the taller tank to your left? they are cylinder and hanging. i keep seeing them on planted tanks and wonder what they are and what so good about them. thanks

Does this reactor have a ceramic diffuser?

Hello.. Very inconvenient reactor if to establish under an aquarium. Hoses are bent. You have all outside, thus it is easier to establish – but not beautiful, when there is a lot of equipment around of an aquarium.

thanks for all your effort producing these vids , very helpful and informative. I’ve not been happy with co2 absorption in my tank’s for ages but watched this and decided to try a reactor. bought one from aquacare and it’s great , plants are growing so much better now. one thing I would say is remove the co2 line when filling the reactor to get all the air out , then replace it when the water is near the top . Save’s messing about tipping the reactor upside down . cheers once again.

Nice video, in future we can open the bottom cap if we use the silicone, thanks for tip for removing air, I used too siphon first

Thank’s

I am using this setup and I am facing an issue. At night when I shut the CO2 off and leave the setup inside the tank I have noticed water reaching the regulator. This can destroy the regulator. So to save my regulator I need to take the setup every night after turning off the CO2 and then insert it again the next morning. Everyday I need to reprime it before starting because trapped air does not start the power head.

Tunze makes a good one but appears to have gotten a bit more expensive in the last 4 years. I don’t remember playing $45 for mine.

Sera Flore active co2 reactor on amazon looks like a good one, I would like to find more info on these reactors, do you set the bubble counter like it’s going to a diffuser? Thanks for the video

love all your information in your vids dude.thanks

Good video. A Co2-reactor is beter than a Co2-Diffusor. But a Co2-Reactor needs a extern filtersystem. If u don’t have a extern filter, use a Diffuser and try to make some waterflow on the Diffusor to better spread the Co2 beter through the tank.
