So here's what I've got. I'm still pretty new to the hobby and jumped right into planted tanks immediately upon getting my first(32g) tank, still have it, still ultimately have very little idea what I'm doing as far as hardware goes.
For my lighting I'm currently using the 24" T8 light that came with the tank originally, combined with a dual T5 24" fixture. The T8 is an 18" Coralife 10k, if I'm remembering correctly. The T5 is... I don't even remember. I know one of the bulbs is from the original combination, at least.
I want to try doing dwarf hair grass again-- last time I had only the T8 fixture, got some runners, and then they promptly browned and died. What would you guys recommend I stick in the T5 that isn't going to kill my wallet and will promote good plant growth? I've got some swords in there that would benefit from higher light, too.
Now, about CO2 kits. I was considering getting the Fluval 20g kit; I've read elsewhere that some people have used 16g CO2 cartridges from bike pumps that fit perfectly. Will the 88g cartridges fluval sells fit the same way? $90 for the 88g kit is a bit much for me all at once.
If there are any other CO2 suggestions that are relatively cheap, toss them my way! I've tried home-done things and it didn't really work out(but maybe I was doing it wrong).
