Question on mixing bulk reef chemicals

[Rus]

Thanks for the info. Ian ,are you selling the bulk supplies at your store? is so do you stock them or only thru orders?

Doug , what is RHF stuff? did you notice your salinity creeping up on you ? Did you find you needed to do more WC's .I do 30gal every two weeks , so hoping that should suffice .What do you figure.

Thanks
