2 weeks ago I set up a plastic bin QT using a file bin so its pretty deep deeper then a 10 g tank this is my nieces tank set up at my parents house . Well I added a sponge filter and an air pump from walmart rated for 5 -10 gallons it didn't occur to me that water depth would be an issue I was apparently wrong. For the first week the tank wasn't full to the top and the air pump worked fine, on thursday I filled the tank to the top to accommodate my new not fully submersible heater because the fill to line was higher then the water level was, I failed to make sure that the air pump was still working. Here it is monday I just got to my parents house and went to check on all the fish after the bad storms we had last night, My parents never lost power but I wanted to make sure nothing burned out do to power surges or anything and noticed the air pump running but not bubbling so I pulled the filter up out of the water to make sure air was moving and about half way up it started bubbling again so Ii put it back on the bottom of the tank and it stopped again so I know its a depth issue. My mom happens to have a case of brand new mason jars so im going to stick 1 of those in the tank on its side and put the filter on there to raise it up hopefully that will keep the filter running until I can get the next size up pump. I also need to do a huge wc tho since the filter hasn't been running properly since at least thursday the fish don't seem to be suffering ill effects but that water stinks. This post doesn't really require responses just posting about how much of an idiot I feel like right now.
