I have a 100 gallon in my garage (cichlids) and it has a light cover but not a full on hood. Anyways my mom recently started smoking again. She prefers to smoke in my garage cause of the weather. I find myself cleaning the outside of the tank of a film of smoke every couple days. Are the fish going to be heavily affected ? Theres a few small holes in the cover where the filter hoses air hoses and heater are placed so im afraid it may contaminate the water. Or should i chill
