Here is a pic of my 20g planted tank from a little over 2 years ago. At the time I was using a Finnex FugeRay LED
, DIY CO2
, API Leaf Zone, Seachem Flourish Comprehensive, and EcoComplete (substrate). It was at the lower end of medium light. I was not ready for a pressurized CO2
system; DIY (yeast based) worked fine for about a year. It was not a lot of CO2
but it made a big difference in the growth and health of the plants. It ran 24/7 and posed no health problems for the fish.
Edit: If I were to do DIY again, I would use the citric acid method. Less messy, longer lasting, controllable, more precise.
