Hi, I am waiting on my new sump to start Triton method on my reefer 170. Currently i am using 3 part solution from red sea. The wired is that i have to add only alk. My ca and mg are replenished by the 1g water chamch a day that i do. I am doesing around 18ml of alk a day. When switch over do i add equal amounts of all 4 elements or i have to add as needed? Thanks.
