First experience with CO2


Recommended Posts

I had a credit from Buce Plant for plants damaged during shipping. Of course, that credit was burning a hole in my pocket. What did I spend it on? The Neo CO2 diy kit. I want to see the differences the  CO2 has on plant development and how they change. It was a fast setup and I was worried that a kink in the tubing might have split the tubing but it didn't. The time for the CO2 to generate took longer than stated, 2 hours vs 1 hour stated. This was likely due to the water I added to the yeast might have been a bit chilly and it took time for the yeast to bloom. I used two packets of yeast as Aquario site stated that this kit is for up to 30 gallon tanks and I have a 40. When it's time to recharge, I'm going to weigh the yeast and only use 1.5 of the packets vs 2. 

I have a lot of slow-growing plants in the tank. You can't see them in the picture but there's also spiral val that has pretty much stopped at 3 inches high (after the 14" height that melted away after planting). They have been in the tank for about a month. I've read that they are fairly fast growers but that hasn't been the case with me. The two new plants are Ludwigia Arcuata and Hydrocotyle Sibthorpiodes which I planted at the back and more under the light

Right now I am pleased with the lighting level, 2-4 hour periods of high-intensity light with 4-hour siesta between. Algae on the plants are pretty minimal and the shrimp keep it in check.  I'm not looking to see what effect CO2 has on algae. I use EG, Seachem Trace, Seachem Iron, and root tabs at the recommended dosing.

How are you controlling when and how much CO2 is being infused? 

The downside of this DIY is it can't be controlled. I know it's imperfect when compared to a normal setup, but it will give me info on whether I want to continue to use CO2 or just when giving new plants a boost.
