Too high nutrients

[Graffiti Spot]

Go read DSR by Glenn Fong.
I have being dosing iron suppplement for a year. And my PO4 is in the range of 0.02 to 0.08.
I don't understand why iron supplement cannot do the job.

Can you send a link to his write-up where he explains this? I have read a lot of his stuff but never saw him mention iron and phosphates.

Even in his calculator there is iron and carbon dosing.
You sure you read thoroughly

Yes they do, I mean I could have better colors and growth but they have good PE, etc



Yup I definitely was going to do this and thanks for the reminder!

If your corals look good then don't change much. Try to maybe up your water change schedule or look at your skimmer and see if there is need for upgrade or process improvement. You start dosing carbon or adding tons of GFO then without a doubt in my mind you're going to nuke your tank.
