It may be very very hard to get an exact small bubble count with just the regulator since the flow will be so great.ok i got it to work!!!! i just put a rubber washer between the adaptor and the regulator. i dont need a needdle valve i think i just adjust the regulator with the knob on top to about 2-3 bbs. so i think im good now. thanks for the help everyone
meh, cheries cost 1$ at most here, look in the classfields... you can get them for 0.50$ if you want... maybe yellow shrimps too(yellows cost alot)my lighting are those 27 watt hampton bay flourescent lamps?(not sure if thats the name). lets see....i think imma have 10 rummynose tetras. haha jk (or am i?).i might get some cherry shrimps(if i have money) if not then amano shrimps.
