I am new to the planted tank hobby and unsure if I need CO2. This is my second tank which is a 32g (my first is only a 5G) with internal filtration (sponge filter, filter pad, polishing filter, chem green, fluval bioballs) using a 180gph pump. I have 7 female bettas, 2 netrile snails, and a rubber lip pleco.
I have hair algae, some green algae and somebrown algae. I have easy plants (at least they say) mainly ferns, Java moss, and anubias. Some of the leaves are yellow. I stopped dosing my tank with flourish as I thought it was contributing to the algae growth. Help needed and any advice appreciated.
