Hi guys, I went to Big Als and Aquagiant and got two separate advice.
Big Als told me that water in edmonton is hard and if i dont have a RO system its not worth keeping discus and look at other options.
While AquaGiant told me that tap water is ok. I just need to put them in a bucket with an aerator for 1 week to condition the water.
I'm confused now. Need more help!!!
