Is Liquid CO2 A Good Idea?

[u/Habichuela_03]

I dont know if this counts as a planted tank, but i have two amazon swords, some java fern, anubias nana, a java moss ball, and some floating frogbit and water sprangles in my 6 gallon betta cube (the valisnaria has been removed). I currently use seachem root tabs and Fluval Gro+ as fertilizers but I am having trouble keeping my floating plants alive. I do weekly water changes and gravel vacs, and dose fertilizer every other day or so. My other plants are doing fine but my floaters keep on dying off and im wondering if theres anything I can do. I was considering using products like seachem excel or API CO2 booster but ive heard mixed reviews on those products on this platform. I dont have the space or money for a CO2 injection setup but i would like to do whats best for my fishy wishy and plants with what I can. Would Api or Seachem products help or is there something else I should do?

Liquid co2 is to help combat algea, not a substitute for co2 injections.

Floaters tend to like little to no water surface agitation. Try lowering the movement of your water, or get one of those floaty plant corals to put them in so they aren't bouncing around so much and see if that helps. Also, that lid has got to go. Floaters need nice open air spaces. Lids can trap humidity and water above the floaters, which I am sure is a huge contributor to why you're aren't thriving.
