Hi eaglesaquarium, Sophie was correct, I never use heater seems the weather here range 25-33'C.
What is you means the hard or soft water? How to characterize it?
DerpPH, u are correct about peoples here. Hard to find there are truly care about the fish even in the certain fish/aquarium shop also. There all about profit & money.
By the way, I'm on my way back from outstation. Hopefully everything is alright. Last I did changed the water on Friday evening.
During my outstation, I had the opportunity to go to an aquarium store & found something interest. There are huge tank & I very like it. I attached some pictures:
