You will also need too dose trace elements , if your not doing water changes as your corals will use these up ,

I'm sure others use something different but myself I use Colombo coral vits and Colombo all in one for dosing trace elements ....

Check out Ty's build thread. He doesn't do water changes other than adding to replenish when he sells frags.

The answer will depend on what you feed and how exactly you dose calcium, alk, and magnesium.

Depends whether you would like to keep things simple or make it complicated.

I have a 65g reef tank on which I do not do any water changes (for 1yr 3mo). Adding Red Sea Reef Foundation ABC+ additive.

Dosage of the powder should be into a high flow area of the tank, perhaps sump, so that it dissolves. Provides Ca/Kh/Mg/Sr/K/I/Br. Note this is not intended to be delivered via drip.

Depending on the complexity of your reef inhabitant needs, you may need to adjust Ca/KH/Mg using liquid supplements. I for one do not have to since the powder works alone just fine. Then again I do not keep clams, etc.

randy i m feeding polylab reef roids and i mantain all 3 levels as i describe in my thread.

Why don't u just do water changes? Maybe 10% once a month. That will make things a lot less complicated. Otherwise maybe use seachem formula 28 once a month.

FWIW, I didn't say it depends on what you feed and products you use because that would allow me to answer, only that it will depend highly on exactly what chemicals are in the foods and the additives. Such data is not generally available, so beware of answers such as "I do this and it works for me" because if you do not use the exact same products, your result may be different.
