I've got a tank that is low light and lightly planted.
20 gallons
30 watts at 5000K (wich gives off a sort of yellowish color sort of unpleasant)
Four plants -Amazon sword fern, dwarf anubus, and two bulb plants I can't identify (they have large bulbs and long flowing grass like growth about a cm wide long runners under the substrate).
Flourite substrate
I've put a flourish nutrient tab under the Amazon Sword as I don't think they are really a low light plant (as the LFS guy told me).
I would like to expand the growth with other low light plants and I wonder... do I need CO2 injection?
I like the idea but I don't think I can live with two 2-liter bottles near the tank. I wonder, can I get by with 750ml glass container (like a wine bottle)?
It will give off less CO2 so I wonder is a little CO2 better than none?
How do I measure CO2?
I've read of the effects of CO2 on water hardness (or is it the reverse?) but I haven't seen KH test kits beside the ammonia and Nitrate test kits. Is there clear explanation of this relationship somewhere? I've read the sticky here about making a reference solution but there is some foundation information I am missing in order to understand it.
Well that has got to be close to the limit on number of questions per post.
Thanks for any help
