+1 - if your corals aren’t consuming it, it can and will raise po4/no3. In my case mostly po4.
I used if for a while. I switched to acro power and notices less impact on po4. - I dose randomly- maybe once a week. But I do not have a lot of big sps colonies - just a lot of frags. I think Ia packed sps and maybe lps tank it would be a bigger benefit then with softies.
on my softie tank- I noticed a huge improvement once I started dosing iodine. But Again: some is good too much is deadly. So just make sure your do your research- i dose 1/2 recommend dose.
there is no magic elixir wonder additive that will make a huge difference. A well established and stable tank is the best - these amino acids are only the icing on the cake in my opinion but must have a solid foundation to start with.
Good luck and happy reefing
