Thanks Wayne for the info. I picked as much as I could yesterday. I've
managed to keep it under control in the past but I guess the VHO lighting
made it take off. Anyone want any it's free for the pickin

If you have tangs eating it, then by simply picking it yourself, it will
make it easier for the tangs to finish it off. Another thing that you can
do, is to keep an eye out for calerpa snails that eat the stuff. Those
snails are grean, and blend in, and will multiply quickly. They tend to be
picky about what species of calerpa that they will eat. You are not likely
to see stores trying to sell them, but if you watch for new shipments of
calerpa, you can often find some, and ask to purchase them.

If the species of caulerpa you have is prolifera,(flat, not feathered
leaves) then I have not found any snails that eat that much at all, and
fish are less likely to eat it over other speices of caulerpa. That's the
bad news, but the good news is that it is the easiest to remove from the
tank with your hands. It's also the toughest, and least likely to crash.

Thanks for the suggestion! I didn't think about blocking an area. I've
been able to keep it under control in a small area in my previous tank
where the rocks with the caulerpa were beforehand (by pruning it and the
fish keeping it "mowed') but somehow or another it really took off when
I set up my 75 gallon tank. I'm guessing since I now have VHO lighting
on the tank it's helping it spread. Several of my fish will pick at it
but it's just not enough to keep it controlled now. I guess I have a
caulerpa picking day ahead of me

Hi Susan,

Don't know if this will help if it's running rampant, but in the past
I've "blocked" the light to a specific portion of my tank by temporarily
putting a a small piece of wood (I guess anything will really work
though) between the glass cover and the lights, over the area that I
want diminished light to. It just took some experimentation to find the
right size obstruction & placement on the glass, without casting too big
of a shadow and effecting anything else. This combined with manually
pruning some of it out may help.

I have to be honest, I've never tried this with caulerpa, but have
succeded with other lower forms of algae by doing this. This way there
are no animals introduced that need to be specially fed after the algae
is gone, and if desired (this is what I did), you can leave one section
where the algae continues to grow, which will make it easier to manually
remove by picking it off the rocks when needed, but maintaining it's
benefits to your tank.

If you try it, hope it works for you.

Patrick
