Humidity?

[ConcinusMan]

Why is it so high? Do you have the water basin as far from the heat as possible? Is it oversized? Is the hydrometer close to it and being influenced by evaporating water? Is their adequate air exchange? Is the humidity in your house high? Just things you need to ask yourself. I don't really need you to answer.

Water is on opposite side. Small-ish bowl. (10gal tank) Hydrometer is in middle of cage, close to heat than water. Screen lid, air is fine. Gasp! MY BROTHERS FISH TANK. darn him.
