Which Co2 System To Use

[penguinpimp1990]

since i dont have nough money to go pressurized, which co2 system would be better for my planted 20 gallon brackish tank. This or this

the second link didn't work for me. But the hagen kit is fine. This is what I used before going pressurised and I still use on my 5 gallon. My only advice if you use this kit is to use your own yeast and bicarb - its cheaper than buying the refills. Although you may not even need to use bicarb.

I'd go for one of these

The hagen units are OK, in their defence you get a nice ladder diffuser with them, you would be better just using that on a larger DIY yeast unit though, but really I would go for this ferplast one, it uses an electrical pump which you can turn off at night giving you a kind of solenoid principle, you'll waste less gas that way and also the diffusion into the tank from the powerhead is very efficient.

How does this system work? and how do you stop the gas from being generated in order to waste less gas as you put it, because presumably the *Energy Ingredients* are just yeast based also, and will continue fermenting regardless of whether the pump is on or not.

Sorry zig I haven't explained it correctly, as I understand it when the diffuser is turned off the glass just escapes from the top and goes to the surface, otherwise as you quite rightly state it will still keep fermenting. In it's defense though you're going to get a better dispersal of gas through this equipment, but yeah you are right on the other front. I guess the only way to achieve that is to use pressurised CO2 and a solenoid.

In my honest opinion you'd be better saving a little while longer and going pressurised because believe me you will spend money on one of these DIY units and then want the real thing later (more expense)

 

[oldwhitewood]

I tend to agree with this, if you get a pressurised system with a solenoid/night shut off value the advantages are its more accurate and easier to set, it wastes less gas and it gives you a degree of control over the water column which you wouldn't have with a DIY setup, disadvantages, well cost mainly, but having a pressurised system certainly gets rid of a lot of headaches.

sorry to hijack ur post

But which pressurised unit would you recommend? ie cheapest and still good/reliable.

sorry again penguinpimp.

oh and i would recommend the Hagen as that is the one i use... (the ladder at least. i dont use the hagen bottle...i use a soda bottle instead)
