I have 24 gallon nano tank and everything is looking great. The problem though is that about a month ago, it stopped working properly. The back chambers are the same level as the main tank so there isn't any overflow of the water. We're getting a large amount of buildup on top of the water that my wife has been manually removing daily. We can't seem to figure out what would have caused this to suddenly happen. The pump has great flow and we've checked everything else. We aren't experts by any means so we may just not understand how to take care of this properly. Any help would be appreciated.
Thanks.
Thanks.
