ferts and co2

[Joefrommi65]

First off has anyone used with Aqueon plant food ? If this is not what works what would be a good choice? Also I have herd that co2 will raise Ph levels is this right ? I am only planting some low light plants in a 20 long .

Co2 lowers pH, making the water more acidic.
Also, check out Seachem's line of liquid ferts.

What types of low light plants are you interested in? More than likely you don't need CO2 or any ferts. Adding some root tabs may be all you need.

Does anyone have a guess how much it will lower my ph in a 29 gal with my ph being @ 8 ?

I guess I am a little nervous because my ph is @8 after 24 hrs out of the tap. How do you do a pwc if it drops alot do you use ph minus to bring the ph down as not to freak my fish out.?

The pH drop from adding co2 doesn't affect the fish.
