I prefer having a big fish tank in our residing room for a number of reasons, however it’s a lot of work. The fish are lovely plus unbelievable to watch, especially if you experience chronic anxiety love I do. But the enjoyment I get from the fish has to be offset by the work that it requires to care for them on a daily basis. Feeding the fish is the least of our worries. It’s carefully removing them from the tank without harming them or stressing them out, combined with the effort needed to drain the tank, disinfect off the algae thoroughly, plus then refill it with water before putting the fish back. If you don’t disinfect the algae always, it creates a musty odor in the apartment that odors love moldy pond water. And if the odor is left long enough without getting cleaned, it starts to permeate the entire house. That’s why I thought our fish tank was dirty the other morning when I observed a gross odor in the house. I was ready to disinfect our tank when I realized something important. The odor appeared after I turned on our electric furnace for the first time in many weeks. I forgot that it was normal for the furnace to odor exhausting after it is unused for weeks at a time. Everything from dust to microbial growth settles on the heating coil while the air conditioner runs while I was in the rest of the year. When it’s turned on for the first time after resting for a while, it has a nasty odor until the buildup is burnt away.
