Good thing Im using ULNS

It's hard to tell if it's Bryopsis from your photo, it looks like garden variety hair algae to me. I was under the impression it has a fern like structure, like this:



When I had Bryopsis years ago I found it easy to get rid of by basting with boiling water, but then I didn't have a forest

Bryopsis can grow very sparsely as well, that's quite a forest ^^^ it can start with single strands and all over... Before you try Algaefix Doug I would do some research if you haven't yet, there looks to be quite a few negative reviews after doing a quick search on Google. Some thing's mentioned are ammonia spikes, loss of sensitive fish and negative impacts on some corals, maybe just softies though. If only the stuff didn't release spores when manually removed, other wise the battle would be much easier

I can see how a nutrient spike could be an issue, that could be a lot of die off all at once. Before I used Algaefix I had scrubbed as much as I could off the rocks and let it collect in a filter sock. I had plucked and dipped for months and was getting nowhere. BTW, I just had hair algae.

First, borrow a Samsung and get a good pic of that stuff to see what it really is
