Red Sea Fish Pharm ARER51034 Aquarium CO2 Reactor Pump Plant Care Products, 500-Liter

Don't waster your money. I wanted a better solution to the delicate glass diffuser for my planted aquarium. This isn't the solution. I found it more delicate than the blown glass. It is made of very thin cheap plastic and is poorly designed. It fell apart even before I was able to get it into my tank and after in my tank kept falling apart. The chamber fell off the pump continuously and then the suction cups quit holding and I found it free floating every day until I took it out and stomped on it. I used it for approximately 45 days so that was about $1 a day. Hope someone comes up with a better design.

It doesnt dissolved co2 very well and frequently release large CO2 bubbles in its opening. One can find better CO2 reactor at this price.

BOught it as a replacement for the glass CO2 diffusers, but I'm not very happy. CO2 is 'collected' and then released as large bubbles of CO2. I tried all settings/flow rates, but can't get it right. Uses a lot of CO2 for the same result as the glass diffusers (note. Got a 80 gallon, densely planted fish tank)

I usually don't post reviews but I saw the ones for this product and felt I had to post my thoughts. I own two of these reactors and use them in a 200gal heavy planted community tank. I use a 10 lb. bottle of co2 and ph monitor to control the regulator. I can push about 5 bubbles per second max and the two diffusers eat it up. If you are having problems with yours it because you didn't set it up correctly. Your flow is two high or you got bad gas pressure.

I ordered thisone for my dad for his 135 gal tank. At first I thought it doesn't work, I couldn't see any bubbles coming out like from the glass difusers, but dad said that's what it's supposed to do. You can actually see it work, I little whirlpool inside it. We planted the tank yesterday and the reactor isn't there for even 24hrs and is just perfect and all plants are producing lots of oxygen. I hope it will stay as good as we think it is.
