so . im wondering if this is a decent place for my heater. or should i raise it? i pushed it down for the whole heat rises thing. get a cover maybe? for all i know snails will get cooked on it or something i dunno my first heater was a thin aqueon that hitched right onto my hob filter vertically so i placed this one inside horizontally . what are your thoughts on heater placement? . i guess also sensors. i had the sense on the opposite side of the hater to maybe even out the temp of the tank. but i found the left side of my tank was always warmer than the heater side. according to those cheap and sometimes free thermometers anyway.
