nope it doesnt count, the evaporation is actually making all the bad stuff get worse in the tank. the only thing that is evaporating is straight up h2o. so think about it, your ratio of h2o to bad stuff is one thing before evap. then after the evap, the h2o gets less and the bad stuff stays the same, so your water quality gets worse with evap. thats why its always good to do weekly water changes.
