Bryopsis Pennata

I've tried hydrogen peroxide on some fags and rocks in the past , the bryopsis comes right back.

That has been precisely my recent experience, unfortunately. And it comes back in exactly the same place. I saw a reference another reefer made about breaking open a rock with Bryopsis and finding ?rhizomes? growing into the rock an inch or two. If that's accurate, it might explain why this stuff is so hard to get rid of - even if you can find something that will eat it, it just grows back from embedded "roots".

My plan for this evening is taking rocks, corals and clams out of my 50, scrubbing the patches and applying 7.5% H2O2 with a brush and pipette to keep it from completely taking over. But more interesting might be the results of deliberately ramping my 20 up to 1.028 and holding it there for a week. There are certainly some corals in it I'd hate to lose, but no clams or crustaceans that might get nuked from hypersalinity.

I've raised my salinity to 1.030 in the past with no effect on Bryposis, however there may certainly be other strains that are sensitive to salinity changes

I wonder if the collateral damage from the peroxide actually provides some decaying organics for the bryopsis to use for C,N and P. When I've treated older frag plugs with coraline on them it seemed to come back stronger.

Hi Elliot that kinda dampens my enthusiasm. Thanks for the information though..

Read a few posts lately about Tech M not working to get rid of bryopsis. I used it to eradicate it from my system over three years ago, and it has not returned. Seems to be more hit and miss than it used to, or more folks that it did not work for are posting about it than used to.

If Bryopsis can send holdfasts 1" into live rock, it's going to be a problem to kill it.

Just realized my salifert test kit for Mag goes only to 1500. What test kits are you all using. I'm going to try the tech m route.

You can still use he Salifert test kit. When you get to 1500, you will have added 1 cc of reagent. Draw up another 1cc, and when you get the color change, use that to see what the level is. If the second cc gives you a 200 level per the chart, then your total is 1500 (first cc reagent) + 200 (second cc reagent) = 1700 total mag.

I believe the above is accurate. Anyone feel free to correct me if I am wrong.

That's right. Just add the numbers from the two syringes.

THANKS AcroporAddict - I'm at 1500 now, I don't have it bad, will continuely remove it and there is one area I'm goint to kalc paste to see if that nukes that problem area

I have been reading up on the Peroxide method. You might want to read up on it!
