Hmm, I only run the tank for 5-6 weeks only. So far the highest temp reach was 34c without chiller.
Using the chiller took too much time to cool
down so had to change to drop in coil which is a great decision!
Placing the tank at the bay window is quite a challenge due to the space constraint and minor algae issue but if manage to solve it, it would a nice feature in the living room )))
