For the people who dose trace elements what made you decide your tank needed them? I've considered dosing them but can't decide if I need to. Did everyone buy test kits like the red sea one to test some of the elements, or have an ICP test done?
If doing a AWC that equals about 10% per week if there any reason trace elements would need to be added?
