same here about the heathmat part they always feel warm to me. but tempretures are good at least thats what my thermometres shows.
i figured out why the plastic of the tank got so hot, it didnt have enough ventilation , now i added some thin books underneath the tank and it cooled off, re-checking temps soon.
i tried to upload some pictures earlier but i notice they take some time to get confirmed by the moderatores since they must get confirmet first on bpforums.
also my current plastic thank is just temp , trying to build a shelf viv tomorrow altough people here said its a bit small from the with so i have to find anoter place.
