oh ye it will take like 10 bubbles per second
just whack up the co2 keep whacking i think the regulator needle valve would limit before the diffuse packs in tbh
oh PS missed a post, the new improved diffuser only the one tube, the double tube is pointless and a waste of money, think about it the pressure has to reach a point in order to diffuse past one tube, but then it hast to reach that same pressure to get through the second tube so in front of tube 1 and 2 is same pressure meaning no difference in diffusion
but, for my new tank i think i will go for the older version give that one ago
may buy both and see if there is any difference
hope this helps
