Ok before I take any plunge; I was thinking of only adding alk (maybe soda ash?) to keep the alk around 8-9 between water change. Ca doesn't seem to be much off (goes from 410 to 380). Or should I start adding that too? I was thinking; instead of going for the fancy stuffs like redsea or aquavitro, why not use the bulk soda ash and calcium chloride?
