co2 bubbles not popping fast at surface.
What does this mean? I am running a DIY co2 unit for the past 8 months with no problem and without this happening... the only difference this time is that I used less sugar (ran out) but bubbles were popping for 2 days of this new mixture. Is it a problem? SOME pop, but a lot take a while, and there is a notiable build up of bubbles at surface. running 2 AC HOB filters so there is a good amount of surface agitation. I did top off the water higher than usual today... I dunno, that could be it too. any information you guys and gals have would be appreciated. Thanks.
