hea i got my water tested today at fish store... (still waiting for test kit)
and they said my ph was perfect.
should i still be adding in my Reef Builder as per the instructions 2 times a week? or will this make my ph go up?
but say i add a toper of water this will make my Ph go down (unlike the salinity, as water just evaporates not the salt) so then i still have to add the reef builder to the tank?
hmmm
me little confused
