how long it take till the water evaporates? i have a 20g long as my sump last nite i filled the sump up wit water where it marks the water level and this morning i woke up around 10am n the water level went lower from the marked water level. at 10am i had a lil bit of more water to bring it to the level. now that im lookin at my sump the water level is half from where the water level is marked from.
