Removed phosphate reactor and thoughts

[chicago]

Tank has been up and running for over 20 years plus.. In that time I have had a phosphate reactor on line. Last week I pulled it out to clean it up .. remove algea build up on it ect. Got lazy and have not put back in. Here is my question.. I am running a Algea Scrubber and the Phosphate is holding at .03 - .05. I have a large Skimmer.
However .. over the last week I noticed some of the green montipora's ... going a bit brown and losing the green colors. other sps doing fine. I am thinking of holding out and not putting back in line.. I spend a good amount of $$ on Rowaphos.
At what number do we believe the phosphate level becomes or has a negative impact.

Lou Ekus shared his thoughts in a seminar.
This is a screen shot of his slide.
He has since upped his thoughts to minimum of 0.05

I believe higher is better than too low. These monti along with the acro on the back wall grew from little frags. PO4 in the tank was always 0.25-0.35

yep.. going to give it a try and see what happens.. tired of changing out the rowaphos. and when I take to long to do it.... always wondered if it was leaching back ?

Phosphate removal media has likely done more damage than good over the course of the hobby. Remove it and let your corals use the phosphate. They will appreciate it

I went full circle, gfo in reactor, got cheesed off with flicking that on and off to control swinging phos, nailed it down with lanthium then now I have to add food to keep it above 0 which suits the fat fish haha
