How much DIY CO2 for 50G?

I am running 2 litter bottles on my DIY CO2, I am not sure if this is enough? Any suggestion? Is this enough?

Thanks

Do you have a drop checker? That could be a first approximation. Generally just look for solid plant growth and reduction of algae. I recently set up a DIY system on my 55 and I'm getting really solid output with a combination of a 1L and a 1Gal glass jug. My drop checker registers into the yellow so that must be getting pretty solid saturation.

You also need to take into consideration how you are diffusing as obviously with increased diffusion rates, you can succeed easier.

Yeah, you are correct Higher. I need a drop checker. I am diffusing with reactor, I thought that would be enough for 50g, but I am not sure.

i would suggest raising the lights even more

slow consistent growth is better than fast growth with inconsistent CO2 (youll have an algae battle on your hands soon) plus your plants will be established for when you get that pressurized kit and decide to hit the gas pedal

Thanks Optix, but are you sure to raise more light? I can get another bulb, but it seems already too much light for me. It blinds me already. Seriously, I am a little concern about algae attack. My plan was shorter photoperiod, less light, until the plants established. The ferts and pressurized will be here in the next few days

oops, guess I was confusing

I mean "raise" as in lift it higher -aka- farther away from your tank to get to the low light region where you hardly need additional CO2 because the plants grow slowly

your foreground plants will reach...but thats ok...after you get ferts and CO2 going...just cut the upward growth and the new plant will cling to the substrate and roots will already be established in your tank
