[HookedOnBettas]

i want to start a new tank with high light plants and i want to know is
Co2 safe to use with fish? any advice will help.

Too high CO2 is bad for plants and fish. Some fish are better adapted to higher CO2. Bettas and cories are adapted to high CO2.

Yep CO2 is fine for all fish.

So I don't know if they are any good but I believe petco has a fluval Co2 system kit. I'm just scared Ill kill my fish .

[Olympia]

Yea the Fluval kit is a good start for a smaller tank. Just because there is CO2 doesn't mean there isn't any O2.

Ok yeah good so I want to put that kit on for a 12 gallon long. Will I need to always use Co2 to keep my plants alive ? Like baby tear grass

[Olympia]

Yea you gotta keep it on. Careful as it will cause a pH drop when first added in.

I'm thinking ill let it run for a week before adding my fish. What thinks will I need to check for when I have Co2 ? Besides ph.
