Additive Suggestions for reef tank

Hi All - I have 120 gal reef tank. I am looking for opinions on who has had good results with additives such as Strontium, Magnesium, PH, iodine, additives for corals and algae. I used to use Reef Pure by Warner Marine Research but I am not able to find this manufacturer online. Does anyone have other suggestions, like Kent Marine, etc. Thanks everyone!

I do not believe there is good evidence that strontium and iodine is useful except for iodine for certain gorgonia. Not sure what you mean by PH. Magnesium is critical for many reasons, but that does not mean that you need to supplement it because many salt mixes have excessive amounts to begin with (but some do not, and need supplements).

Don't be fooled into thinking these supplements are magic bullets. Many do nothing useful.

Supplementing calcium and alkalinity is critical. I also dose iron for macroalgae and silicate for sponges, etc. Not much else, and generally, that is true for many folks who have run their tanks for a long time.
