Ideas?

Get the smallest yellow tang you can find. I have had one in my 37g for a year now and he is just fine. By the time he gets too big you will problably be in the process of upgrading to a larger tank anyway. If your addiction is as bad as mine you will go bigger sooner or later.

Thanks for the help everyone! Now I feel more confident that I can get a handle on this and control it by natural means.

Fwiw, I think we will be calling about the seachem test kit this week once I have Barry check to make certain about my results both on the reference and tank tests. Thanks for the help Jenn!:up:

Just to add...I'm with Gary in increasing Mag levels.

I had some of the worst HA ever in my 65 gallon tank. It just about took over the whole tank and killed most of my corals. I tried a number of things including Algaefix. That helped but was only temporary. I'd stop dosing and it would bounce back stronger. What finally eradicated it was increasing my Mg to 1550 (was about 1100).

One thing to note, Gary was able to beat his HA using non Kent Tech M to beat the HA. I used Kent Tech M as I had it around from bout with bryopsis in my other tank. You mileage may vary. Here's my thread with before and after pics:

I thought that was only effective for Bryopsis... which this isn't. If it works on everyday GHA, I've learned something new today.

I think it depends on the specific species of HA. I believe some are more susceptible to increased Mg levels. GNashty (Gary) used what he had around though it wasn't Kent Tech M. He got rid of his HA. I used Kent Tech M on my infestation and was able to get rid of it and have now been clear of HA for over 2 months now.

My HA was believed to be derbesia which is suppose to be Mg tolerant yet it just melted away when I increased my Mg levels. I'm guessing that it was something similar looking but in fact a different species.

This is of course just based on observation rather than scientific fact.

I'm not sure what this is... it is much shorter than yours (saw your thread), and definitely not bryopsis... it resembles green moss growing on a rock in the woods.

If there's one thing true...there is no one true answer in this hobby!! :lol2:

One thing I should add: I now run phosban reactors on both tanks to remove phosphates.
