Thanks for the fast replies!
I know nanos take a lot of work to keep levels and such correct. I used to own a 30 gallon reef tank - not super small, but still needed attentive care. What I meant was more like... saving time during water changes and cutting the time to complete the set up money wise?
Idk. It's either going to be a nano under 10 gallons or a 20 gallon set up. I just love the way some of those nanos end up looking!
@ bitFUUL really now? I see that they have CO2 for larger systems as well. What's the difference between the ADA & the GLA systems?
