I'm loosing the war with GHA, help?!

[Skimmin]

You may want to try is dropping your temp and salinity. I had the same problem at one time. I dropped my salinity to 1.020 and temp to 76. Another thing I also found that helped was adding lots of inverts and snails. I haven't had a single spot of that crap since I did these things. (in a 78gal tank I have approx 80 crabs and snails) I understand how frustrating it can be though. Good Luck!

I battled hair algae for a year and a half. All I can say is patience, keep doing what your doing and eventually it will go away.

At this point it is probably no longer a nutrient issue, It grows because its there. Have you ever seen a dandelion growing and flowering on what appears to be solid rock?

Greg,

Yeah I did try your suggestion, I got a whole bunch more hermits, starved them (they seemed really happy with it ) then toseed them back in the display, they are more active, but not so much in the hair algae department.

I searched out seahares, and could only ever find big ones. I was prepared to swallow my fear of them toppling my frags, etc. but instead found an urchin and went that route. The urchin does really well, as in it literally strips the algae off the rocks, but it can't seem to keep up.


Skimmin,

I am not able to make those types of adjustments, my tank is fully stocked with 9 clams of various species, a large selection of SPS, and LPS corals, I also have a large clean up crew. I would be afraid that a lower SG would kill my tank.

Do you have any literature about GHA, and lower salinity, or lower temps? In all my research I've never before come across this suggetion.


tknude,

I do prune at the same time I do water changes. I ensure that 95% of what I prune does not make it back in the tank at all. I'm pretty good at pruning it in clumps, with very few stray pieces getting into the system. I did tear down my whole system a few months ago to scrub all the algae, and it didn't seem to have any effect either. How bad was your hair algae problem? How many months have you been battling it?


Chaloupa, and Marie,

Thanks for the encouragement. How long on average did you battle green hair algae Chaloupa? Was it bad like mine? There are recent photos in my tank thread. This stuff is just really pushing my buttons. It has literally reduced my usable surfaces for frags by probably 30%. I just wish I could see some sort of end in sight!

Go to your LFS and order a small 2 inch or medium sized sea hare. Large is not the only size that is available.

Just so everyone is aware this thread dates back to aug 2007, I think her hair algae problem is beat

Thanks guys. Yes the problem was beat a LONG time ago....

What is with people reviving my threads from 2007 this past week? Entertaining, but really strange.

[Mr. Fairy Wrasse]

OK so how did you get rid of the GHA in the end???

I second dropping temp and salinity. I remember reading it in some book/literature. I tried it once and it helped

[Der_Iron_Chef]

Do you run lights in your refugium on a reverse cycle? In other words, does your PH remain constant?

I know that the higher the PH, the lower the levels of dissolved Co2, which would help (in theory) to reduce algae growth.
