I totally agree. I made a mistake and am fully responsible. lifestock is of course way more important.plants our fish ? Chose one.
Saying this... if one get's the advice to increase co2 levels... and increase even more if plans are still stunting... people will push things too hard and shrimps will die. I am sure that I am not the only one who made this mistake.
What I do realize now, is that with more surface agitation you can get away with more co2. (thumbs up for the vortech!!!)
I do not only think it, I know it It is pretty hard to do statistics on n=1I think it helps if you have multiple aquariums also.
I don't know, but in about 6 really amazing tanks I measured around 50 mg/l.what is the limit for co2
