hey guys my native tank is way to hot and i have no clue why its only been like in the 70s here and its like 80 degrees my fish are really dull in color compared to when they are in colder water and i want them to be healthy and happy but no way i can afford a chiller so what should i do i can take out like any ammount of water everyday and replace it with cold water if i need to do that i think that is my only option i can think of i cant run and air conditioner in this room either so anyone have any ideas on what i could do let me know thanks im going to probably take a large ammount of water tonight and replace it with cold water
