| Re: Help-Skimmer Causing Tank to fill with Bubbles New carbon causes bubbles per the flow chart. I noticed in my new tank that the new carbon filter was being sucked up right to the bottom of the circulation pumps, and immediately the pumps would send out a burst of bubbles. I had to turn the pumps off a few times and let the carbon filter drop back down, then turn the pumps back on. I had to do this about 5 times before the carbon stayed down where it belonged and the bursts of bubbles stopped. I also adjusted the level of the overflow box. |
