I added another dose last night which now brings be to about 21 days of treatement. My hair algae is pretty much gone. Any that is left is pretty much dried up and disintegrating. I may do one more dose and then see how it goes from there.
I'll give you a little more detail on my livestock. I have two sea stars, a blue starfish, hermit crabs (multiple types), Sally Light Foot, camel back shrimp, cleaner shrimp. For fish I have multiple types of tangs, lawnmower blenny, watchman goby and three dwarf angels. I also have a live sandbed.
Again... The only side effect I noticed was on my sponges. I have four branching sponges that seem to have developed some white areas. I'm not sure if that's even related to the Algaefix but it looks like I will lose one of the sponges.
I have not seen any side effects on corals or fish other than the sponge.
Some have asked on this post if it will effect a refugium. I don't know that answer as I don't have one. Definately something to think about.
Thanks
