I have recently been researching plants (as I want to do a planted betta tank) and you do need to have a co2 pump and plant tablets! (The fish poop isn't enough) I have learned lots of this from aqua pros and aquarium co-op on YouTube! (Sorry I don't know a lot to tell you)No but the co2 should be given by the fish. Right?
It has only been a month since my substrate came. My aquarium is one month old. Will stopping my bubbler help with the co2?THe plants you have are demanding when it comes to co2 but the brown spots are caused by old substrate. When was the last time you changed the substrate? You may also need root tabs and flourish iron, flourish potassium, flourish magnesium and flourish excel. If you can collect all of these and dose a different one everyday they should perk right up.
