From my understanding @Brian K dual stage keeps from having the end of tank dump I believe I am sure some else can chime in.
@Ryan W thank you for your help I order Fzone the C02 art copy or rebrand got it yesterday seems to be made really well and price was good for me and had good reviews also has where I can run to aquarium a so that is cool.Waiting on my diffuser to come in. I 2as lucky my grandpa had 2 old ⁵lbs tanks laying around and I swapped them out yesterday only cost me 22 buck for both. So I am about $175 bucks to get up and running. I will let you know how it is.
