Commonly used additives

[flipperaust]

Hi all,
Apart from your dosing chemicals what other additives do most people use in the USA? I see that your TOTM winner uses Tropic Marin A- and K+ but we dont even get it. Zeovit seems to be used a fair bit but its very time consuming.
So I am just after your thoughts. I hope you understood my Australian accent? :lolspin:

Many people use little to none aside from calcium and alkalinity (and various things that may be better described as foods or nutrient export methods, such as dosing organic carbon sources).

Aside from that, I only add silicate for sponges and iron for macroalgae.

This has more on what I recommend (and not):
