iTrader Positive Rating: 100% Plant Points: 61620 | Re: Tiny super efficient CO2 reactor Haha! Soon this thread will reach 1 million pages. It's both amazing and pathetic how cheap are we, the planted tank folk.
But the truth is these little reactors work really well. The biggest tank I've seen using one (only one) of these is a 75 gallon and obviously the plants are getting enough CO2. And this is with a temporary crazy water flow of about 800 actual in-tank gph.
I'm about to try only one of these reactors in my 180 gallon tank. I suspect that it may not be adequate but we will see.
So let's see who's next in this battle to prove who's the cheapest plant nut, haha.

iTrader Positive Rating: 100% Plant Points: 17850 | Re: Tiny super efficient CO2 reactor I just set up a 2 gallon hex tank with one of these reactors -
I ditched the included undergravel air powered filter, and coated the included light hood with aluminum foil and then put a 10W CF bulb in it (it looks to be about 10000k which is a bit blue for my tastes, but it was $5).
Total damage: $40 (including check valve and thermometer and airstone).
Its a pity that I can't inline these things, or else I'd use it for my planned 1qt pico. |

I need to get on the ball and make a big bottle of DIY CO2 for now for my 75. I did everything per instructions but added a small 3/4"x2 mini Air stone inside of it. I also used Stealth tubing to hide it in my tank. |

iTrader Positive Rating: 100% Plant Points: 44850 | Re: Tiny super efficient CO2 reactor I agree. Just built my first DIY CO2 reactor also. A 1 gallon jug from some apple juice with the mix listed in the article. I need to go get some more parts. I will probably upgrade to the Red Sea Paintball kit as that will fit in my stand with my sump.

iTrader Positive Rating: 100% Plant Points: 2350 | Re: Tiny super efficient CO2 reactor I just setup one of these today and was wondering if most of yall are using the sponge at the outlet? From what I can see, once the co2 hit the impellar it get chop up and disperse onto the sponge and finally it push out a little bit and the rest of the tiny bubbles just float up to the top. Would it be better if I take out the sponge and let it shoot the tiny bubbles throughout the tank? Thanks. |

Plant Points: 300 | Re: Tiny super efficient CO2 reactor I found one of these pumps at my local PetCo, so I got it purely on the fact that I saw it used in this thread, and decided to make a CO2 system for my tank.
Only concern I have is the pump is a bit loud when the bubbles hit the impeller. I was thinking if I got a second small sponge and put it inside the filter, between the CO2 tube and the impeller, maybe the big bubbles would be broken up into smaller bubbles before hitting the blades and it wouldn't be so loud - but then again it might make a lot more noise if the smaller bubbles still produce the sound.
Any advice? |
