Just got my pressurized co2 setup! Finally! No more DIY co2! I got a free 36# tank from work! Anyways, Just wantin to know about bbs...Oh, and I have to mention I bought a regulator from Rex Grigg and it works great!
Start with 1 bps...then go up from there until you hit your target point.
We can only suggest a standard to start with...not what exactly you should have. There are many intrinsic properties of each individual tank that dictates what the bubble rate should be (i.e., plant density, plant types, lighting intensity, etc). (I don't even have a bubble counter anymore...)
