Which Fan is quiet?

[JeffL]

hi guys thank you very much for your contributions, I guess will try out GEX first.

just another question, since using fan will evaporate the water really fast and we need to top up everyday. Isn't it dangerous for the water parameters?

Use distilled water.

Or to remove another bit portion of water before adding clean water. Partly to remove some of the chemical left behind after evaporation before adding water(if not it will become adding more chemical). Also can work as a little water change everyday. This may prevent Kh n Gh from rising i believe. Lets hear from shifus out there.
