thank you guys again ...
for some reason, I couldnt find the temp needed for potbelly.
to be honest, I dont think I can ever get the 75G custom tank I have to 59 F lol cost of running a chiller on it all the time is not doable for me lol so gonna stay away from them for now ... perhaps when move to a house witha cold room or a cooler basement lol my condo temp is about 72.
thanks again
