All 3 tests have my phos at .25 for the past 3 weeks Salifert, Red Sea and hanna
Naturally, I have added gfo. Since that number has not come down, and conitnues to stay at .25 I keep adding a bit more gfo
The result is the same.
Now here's the rub... I'm starting to see dinos and some corals are starting to pale, stuff that I would see low phosphate.. What little algae I did have is all dead. My macro algae is still growing, but has slowed....
What should I do and why is phos # not changing despite adding more and more gfo?
