Great looking tank and the journal's given me all sorts of ideas with how to handle my little tank if ever I need to start it over from scratch (i.e. if I can't fix my current mistakes).
Out of curiosity, how long would you expect the CO2 canister on the Advanced system to last? I'm trying to figure out whether I could get by with a smaller paintball setup or if a 5lb CO2 tank would be the better bet. I've got an 8 gallon tank with 7 hours of light per day from a 13 W compact fluorescent. (It's a Fluval Ebi and will eventually play home to shrimps once the plants grow in healthy enough to provide adequate cover. First tank since I was 10.
) It's a little more underplanted than usual right now because I had to heavily trim down the dwarf hygrophila in the back because it had started to rot and lose all its leaves at the base of the stems.
Keep up the great work! Looking forward to see how your nano keeps evolving! And thanks for all the info so far!
