Hi, How Do You Know Your Co2 Is Sufficiant?
I got my water parameters to PH 7.1 and KH of 4.5, I have CO2 injection. How will I know the plants are sucking it up? I have good plant growth (except for my Crypt. Wenditti and Sag.)? I dont have any Riccia or Gollastigma that pearl, is my Ludwigi supposed to pearl or my giant Hygro?
I guess my question is do plant need to be pearling in order to know if they are sucking up the CO2?
