i have a 55 gallon tank that i just added a rena xp3 and aquac remora skimmer on to, but since i have the temp has increased to about 82 degrees. i was keeping it around 78. the house is a cumfortable 76 and im pretty sure the added heat is from the skimmer pump. it uses the maxi jet 1200. i noticed when i used it to mix up some fresh water that the water was quite warm. i was wondering if anyone else had problems with this pump and also a good replacment pump for this model skimmer. thanks, dorian :?
