Co2 Review
My qquarium has been having a number of issues lately, I had a pretty nasty infestation of blue green algea (cyanobacteria) which I'm controlling with more frequent water changes, and feeding less. I tried to get a few bottom feeding corys (we got a number of swordtail livebearers at the same time) but none of them did very well in my tank, in fact I think I only have 1 or 2 of the swordtails left.
I think they would have done better if I had more plants and hiding spaces in the tank, because these angel fish are starting to get a bit agressive, but my plants have stopped growing as rapidly as they once did. Also, some of my broader leaf plants are starting to turn a bit yellow and my water pH has gone way up, near 8. The angel fish love it, but that's a little too basic for my purposes as a community tank.
Since CO2 injections will lower pH, promote plant growth, and discourage algae growth, I think that's what I need to do to get the aquarium I see in my head. (more…)
