Dosing

[Jack Sparrow]

Hi I have a 5 gallon fluval aquarium with 4 species of lps coral. I have a hammer coral with 4 heads, a frogspawn with 1 head, a candy cane with two heads, and a sunken coral with tons of small heads. I am now using reef crystal salt will a weekly 1 gallon water change be enough for them to grow happily or do I need to dose elements. If so which elements and how much.

It depends on the corals uptake of elements. Are you testing calcium, alkalinity and magnesium? That’s really the only way to know. Usually water changes until the change can’t keep up with depletion.

Testing is the only way to tell. Ideally twice weekly should be fine.

That small water changes are everything. You have to test for values first
