DIY D201/301/501 CO2 units
Hi, has anyone used one of these diy CO2 systems sold online/eBay? It has needle valves and uses citric acid instead of yeast and from the little info I can gather, critic acid is much more consitent.
I am mainly looking into this as I don't want the fluctuations associated with the yeast method = algae issues.
If anyone has any experience with these units or any input would be greatly appreciated. Thanks.
