My long term results are not so good. There were a few corals that weren't too happy during the dosing. As time went on, a number of the LPS started to recede. I believe that the Algaefix does weaken the corals to an extent, which may allow infection to set in. The corals that I'm having an issue with are War and Peace favia, some kind of green favia, Wellso brain, most of the Lord Acans, Acan Rotundofloro, Micromusa, Green Mycidium and the Tyree Red Watermelon chalice. The RW is showing a small amount of skeleton in one area, which does not make me happy. I had first noticed that some of the LPS were not eating like they should, then the Micromusa nearly melted overnight. I checked the Lords closely, and saw that there was a white mucus forming at the edges. After re-checking parameters, changing carbon, doing a large WC and Furan2 dips it looks like it may me under control, I hope. I had tried Algaefix shortly after I had started my first reef tank, and had a similar experience with Acans receding. I wasn't exactly sure what the problem was at the time, but now I'm having the same problem I had then. Up until this point, I've had zero issues with any of the LPS. The kicker is that I still have the same green algae that I started with. If anything, there is more of it because all of the other types of algae are gone, lol. After stopping the Algaefix in the FOWLR, the algae growth really took off. I believe it's because the chaeto is also weakened by the Algaefix, and the algae in the tank was quicker to recover after the dosing stopped. The chaeto in both sumps was reduced in size, and a good amount had sunk to the bottom and appeared limp and possibly decaying. So, off to do another Furan2 dip. I would have posted sooner, but work has been extremely hectic lately, and I've been dealing with this problem.
