Will A Venturi Drive Co2 From The Tank

[Onderdole]

hi i normaly use the venturi tube that came with my internal filter.

I like the bubbles in the tank and supposedly it improves O2.

I have it placed 3 cm below the surface so the surface is not masively disturbed but is moving gently

reciently ive put 3 plants in the tank

2X Myriophyllum aquaticum ( parrot feather)
1X Hornworth

will usign the venturi as i have described drive out Co2 and cause growth issues for the plants

20 gal
fully cycled cold water tank

They should be fine (providing you have a the correct balance of light, nutrients & CO2)
