Electric CO2

[plumboy21]

Recently saw this electric CO2. Seems that it uses electricity to charge carbon filter to create CO2, didnt really read the package though. Anyone has use it before coz i am interested to purchase one. Perhaps we can control CO2 better if it can be switch on/off, say using a timer? What U guys think?

you can't effectively control the amout of co2 that is being injected. There's only a few mode to choose (if i remember clearly 3) but doesn't seems to make much sense of the co2 input.
I've used it before, really not as useful as you imagine. Co2 cylinder is still the best. I've forsaken the electrical co2 and am now using the cylinder. No regrets at all

I've seen before. But in my opinion it ment for nano or even 1.5 shrimp tank.
I dont think it is sufficient to supply for bigger tank. Co2 cylinder still the best for bigger planted tank.

Hi AQ, regarding the electronic co2, anyone knows how it works ?? Can the carbon/electrode be replaced upon depletion ?

[SmallFish]

Yes it does. One carbon plate can last between 4 to 8 months.
Afterthat, you can replace with a new one.

Good thing about electric CO2, less hassle, cleaner, and does not need much space. Only flipside is that you cant really control the amount of co2 except to try n error over time (theres a control knob to control the output) to see which level of output results in healthier growth in ya flora and no gasping of air by the fauna.

Basically, the carbon (C) reacts with the water (H20) to release co2 into the water while releasing hydrogen bubbles (those bubbles you see streaming out of the electrode are actually hydrogen gas; don worry, they wont kill your inhabitants or explode :P)

btw, i m using one and hv an unused set on standby if you are interested to buy.

cheers.

not a cost effective solution when compared to pressurised cylinder.

Electricity + water is never a good match... And there is always a risk of an dangerous accumulation of hydrogen gas...

Anyway, with this, you might run into difficulties in finding replacement cartridges, the right CO2 amount etc... Why not invest in pressurized CO2?
