Lighting power and plants?

[Danyal]

Actually, CO2 affects you pH always. The more CO2 you have, the lower your pH will go. CO2 does directly affect your O2 levels as well. CO2 and O2 are both dissolved into the water, which can only hold so much. Take into consideration your different nutrient levels which are also in that space. Then there is the part where the CO2 is converted into O2 by the plants. So depending on how good your setup is, and how many plants you have, co2 can actually raise your O2 levels.

my bad, i knew co2 lowers ph but i never really got around to learning the finer details, i was more interested in lighting and equipment.

Read the stickies about The end of WPG. That will explain in depth much more for you.

why is it closed? i've got some questions i want to ask, i'll agree that it works a lot better than WPG but sometimes i think people seriously overestimate how light needy some plants are, i've had riccia growing submered under a 13w cf bulb when people kept telling me it was a high light plant that needed co2 to grow. i need to get back onto plantedtank

well i ask about glosso because it looks like a really good looking carpet plant while riccia needs alot of maintance and im scared that if i use java moss a very small piece may fall of and get sucked into my filter (aquaclear50) and start glowing in there.

Do any of you have a good looking plant in mind that can be a very nice carpet?

perhaps some liverworts?
