Granular ferric oxide and its effect on bryopsis

Bryopsis has been a ruthless algae that is nearly impossible to get rid of for me. Some remedies are magnesium spikes, h2o2 dosing, and vigorous water changes.. But what if none of that works? I've gone as far as getting rid of all my fish for 3 months to try to cut down on nutrients. It worked for a little while, but when I added a clown, it came back. I'm about to buy a Gfo reactor, has it helped anyone else in the battle? I'm close to giving up at this point, I need some help.

I have a lot of bryopsis growing in my algae scrubber. It is very tenacious. I am unaware of anything I have that eats it. Because of the scrubber, the algae just grows in the scrubber and not the reef. I pull it out by handfuls and throw it in the garbage. Pretty good nutrient exporter. I would say your only choice is to reduce organic levels beyond where they are now. A GFO reactor might help.

Also people use tech m by kent. Not sure why but it gets rid of it. I used it and it worked. Just buy a mg test kit so to not overdose. You use double the amount as in instructions. But check your mg before starting.

And I have a gfo reactor and carbon reactor and biopellet reactor. With these running and nitrates were undetectable as were phosphates.

Yeah.. The worst case scenerio is that I sell my coral, crush up the rock in the display, and put it in my sump. Start with all new base rock.

I did that, it slowed down growth, but couldn't completely kill it :/

Well I hope the Gfo reactor helps. It doesn't really seem to kill it off completely even with low nitrates and phosphates for me.

It can grow on almost nothing. Very efficient algae.

Yep, which is why I'm unsure what to do. It's definitely hard to keep my tank running knowing that the algae will just grow back and kill corals. I don't have any algae other than it.

I have watched healthy corals beat it back. This is a super common algae on the natural reef.
