Hair Algae

[bowen1022]

So after Spurilina I think I may have hair algae or similar. I noticed some on my hermit a while back and didn't think much of it. Recently I have noticed more of it showing up all over my rocks. I know that hair algae grows in mats but this isn't growing in that way. It is growing a few hairs from a bunch of different single spots. I don't have any good photos of it at the moment.

Treatment:
I have heard Kent Tech M is good for raising mag but I've also heard that recently they changed the formula so it doesn't combat hair algae/bryopsis the same. Does anyone have any further info on this? Can it be defeated with H2O2? Also I have another tank that I can set up if there is a way to assure my frags don't carry it over. Thanks

Do a test rock


The new way of algae control not written in any book is we should stop testing algae modes on the innocents in the tank, say corals that don't have algae on their polyps. Lots of algae control methods involve doing X to the whole tank and cross fingers non targets do not die


We can do better now

Take out two rocks and dump peroxide on one patch of algae removing none, then on another dump the tech m just the same. Rinse em after 3 mins cooking outside tank. Put back in still removing none, then compare results in three days before doing anything to the whole tank. Start by dosing nothing to the water and act directly on the target is 2016 -> algae control

Model some direction first with two test rocks while you hit the common modes of less white lighting intensity, low nutrients, no rotten sandbed etc
