This tank is awesome too. IMO, forget the co2 if the shrimp are your priority. It just adds another thing that is making them unhappy so if it's not necessary leave it be. Nice find on the 2213, you will be very happy with it. I couldn't do an Iwigumi tank, I love lush thick plantings and Iwigumis are to minimalist for my taste.
I'll probably end up just letting everything grow in there! lol. Hard to resist. I guess that's why a really nice, true Iwagumi is hard to find.. Yes, I think I'll take your advice and ditch the idea of C02 for this one.
