    GLA CO2 reactor makes a HUGE difference!

    After seeing a video about the comparison between diffusers, inline diffusers and reactors for CO2 addition to aquariums, I decided to give the GLA reactor a try. The CO2 levels are really easy to control, and my water is CRYSTAL clear (which means that CO2 is making it to the bottom of the tank because it’s totally dissolved in the water)! Love how this makes my tank look and my plants and fish seem to love it, too!

    Amazing product!

    GLA I never doubt quality is always top notch. I have only been running the reactor for about a week on my IAPLC tank and I see great growth and daily happy plants. Showing good pearling and such by day end. To me it shows that they are getting plenty of what they need. Love it is quiet and no co2 bubbles in the tank and waste of co2 isn’t there! I’m very happy with the purchase and will probably be buying one for my other tanks as well!

    Best co2 reactor for your planted tank.

    Works absolutely flawless. Co2 is stable all day and the best part, no bubbles! A+

    Absolute beast of a reactor.

    Quick delivery and works fantastic. Installation was elementary and took a few minutes. My 80g tank is 100% clear of co2 bubbles. My last reactor had to be burped of co2 daily. I had GLA help me dial in my co2 system and my tank has never been more stable.

    Aquarium co2 reactor for planted tanks you cant pass up.

    Great bargain for getting all your co2 100% saturated. It was easy to set up and my co2 is far more stable. You can view this data if you use a pH controller with an app interface. The difference I see is amazing. My graphs are much much more steady and not like a roller coaster. I had no idea. Im using reactors from here on out.

    Quality aquarium co2 reactor.

    O looked at all the other reactors on the market and this one was the largest of all the ones I viewed, so I ordered it. It works exactly as GLA says and absolutely no need to burp out wasted co2. This thing saturates the co2 100%. You will be pleased 100%.

    I love this co2 reactor.

    I waited until fall to order this reactor and could not be more pleased. Instructions were super easy, you dont really need them if you have half a working brain. My tank is now crystal clear and not a bottle of seltzer water lol.

    Simple and effective.

    I wanted to try a reactor with my new GLA co2 system so I figured now is hood a time as any. Prior to my reactor I used a misting diffuser that creates a very fine mist of co2, the plants loved it. The crazy part was my cat could see the bubbles and they attracted her to drink water from my aquarium. In came this reactor. Water is crystal clear right from the start. Real basic simple installation. Two hose barns and one co2 connecting point. Works great and loved the GLA support team.

    Super co2 reactor!

    I love this reactor, its so much larger than I anticipated but I feel thats to its working advantage. It saturates the co2 100%. However do know you still will want to clean the inside of the reactor after a few months. It grows the same bacteria that grows inside your filter. I did tno notice any reduction in performance when it was dirty, it was just unsightly. Otherwise a fantastic co2 reactor. Easy to follow instructions and the stickers were cool!

    The best planted aquarium co2 reactor.

    I switched out my previous reactor because it kept filling up with gas and you had to bleed co2 out all the time. I feel it was the design, perhaps to small. The GLA co2 reactor was very large in diameter compared to my old one. The whirlpool effect is really cool. 100% saturation and tuned just right.

    Excellent aquarium co2 reactor.

    I went from a DIY PVC reactor to this beast and what a difference. Its much larger than I thought it would be but its perfect. It comes with a check valve a small section of connecting tubing. You will need your own co2 tubing. Otherwise I love it, and the cool stickers that came with it!

    Much larger than anticipated and works like a dream.

    I was unsure what method of diffusion to use so I phones GLA via text and they helped me narrow things down to an inline co2 reactor. my tank is crystal clear now, no more foggy mist from the ceramic diffuser. I love the fact I dont have to clean it if I dont want to so my co2 levels are always on point 24/7 in my 90g.

    Much better than my old co2 reactor.

    I ordered this to replace an older reactor that could not be cleaned. The GLA co2 reactor is massive in diameter so you can clean it in seconds easily. During operation this thing functions flawlessly.

    Very happy

    I love this reactor and it does exactly what a reactor should do. I learned a lot from GLA on how to properly dial in diffusion per the light levels in the tank. All while considering off gassing/surface agitation. Excellent co2 reactor!

    Exactly what your looking for.

    Easy to set up and maximize your co2. Keeps the equipment out of your tank.

    Wonderful!

    I love this reactor. Very well made and could not be easier to install. I like that I dont have to clean my diffuser any longer, one less thing to do. It works just as intended. Totally saturates my co2 in seconds. The cool whirlpool motion has my cat mesmerized. The reactor is quite large, much larger than I anticipated only because I compare it to my previous reactor which appeared to be a DIY type reactor from another vendor. I reached out to GLA to have my reactor custom fit with two different hose barbs. If you need one for a 2217 filter they got you covered. Sweet co2 reactor no doubt.

    Extremely happy

    This reactor has been perfect since day one. Ive had it over a little over a year now. I can now see crystal clear water and have perfect co2 levels all day. It does take some getting use to if you new to using a reactor vs a co2 atomizer. One thing to note, reactors will use more co2 than an atomizer. This is to be expected because your aquariums water surface is an instant escape membrane for co2 to leave solution instantly. Whereas an atomizer keeps co2 mist in the tank for the most parts and the tiny bubble stick to the leaves and plants which they love. This is why atomizers use less co2 in most aquarium settings. I have the 16/22mm on my 75g tank and the 12/16 on a 55g and both use about the same amount of co2. cant wait to set up my new 125 with another 16/22:)

    Perfect fit

    This reactor works perfect, and fits my cabinet really well because it stands on its own. It has my co2 saturated 100% and you barely have to do anything lol. It came with easy to follow Ikea style instructions, so if you have trouble its nobody fault but your own. Its a little expensive but the customer service and the whole experience was just super pleasant. The guys at GLA are stellar, and are always on tap to help. These guys are legit Co2 pro's. Not some posers like the rest of the stuff you see.

    CO2 reactor

    I just set a new tank got an additional manifold block. I want to try out the co2 reactor. I read a lot about how efficient the co2 reactor is. I wanted to give it a try. I like the fact that the reactor is very big and stand on it's own. I added a small pump to the reactor. I ran the return hose line into the sump pump. The first few hours the water is swirling inside the reactor. So it makes a lot of noise. Once the reactor filled up. There is absolutely no noise. On the positive side to the reactor. You don't have to see the tiny bubbles floating all over the tank. You don't have to maintain it like you have to with the atomizer. I have been running it for a few weeks now.

    Very Happy

    Excellent build quality and easy to follow instructions. It takes all of 3 minutes to install. This co2 reactor is much larger than any other reactor I have ever seen or used. Perhaps thats why it works so well. The way the whirlpool motion happens inside the co2 reactor is quite cool. This is what gets the co2 100% saturated. I run a fairly high bubble rate on my 180g tank and this reactor has no issue handling this tank. I will be buying another one as soon as my tank arrives next week. Very happy!
