DIY hig-tech CO2
I'm new to the forum and very new to planted tanks, so bare with me.
I want to get into using a high-tech CO2 because I've read a lot about inconsistency with DIY Yeast. I'm a student though and can't afford the $300+ Red Sea setups or other such kits that Big Als etc. offer.
I have read into DIY projects though. There are dual gauge CO2 regulators used for beer brewing on eBay for about $50. Also saw an Azoo CO2 regulator kit with solenoid on eBay for $100 (is that a good deal?).
I only have a 25g tank and am planning on going within the area of 2.5-3wpg but because of space might be more likely to try a paintball CO2. I realize yes, it will run out faster, but I live in a small suite (student remember?) and I would just have to buy 2 paintball CO2 canisters.
Anyone have any experience with a DIY project such as this and can you give me any advice/re-direct me to any links that give instructions/websites that have cheap parts/where to find cheap parts etc.
