I'm sure this has been hashed out long before my very recent arrival on this site...but I'm about to embark on a first time aquascape project and want to do the best I can for the money I have available. I'm planning to utilize an AQUATEK CO2 Regulator Mini on 20 oz. paint ball bottles ... what's the community view on the quality and effectiveness of the Aquatek mini system? I've got a 29 gallon tank and it'll be heavily planted with appropriate lighting. The main reason I'm looking at this particular system is the ease of getting paint ball bottles filled and any major sporting goods store...and cheaply.
