Byropsis

[stl_rock_guy]

I've realized that i have some growing in my tank. It's not bad yet but i want to nip it in the butt before it takes over my tank. I've read that using kent marine tech m to raise mag levels over 2000 ppm will kill it. My test kit (salifert) only tests up to 1500 ppm. Does anybody have any other suggestions to get rid of the byropsis or a way to test my mag levels

Get another syringe full of MG3 reagent keep adding it until the color turns. Then, just add the second syring reading to the first.

I had bryopsis for years!!! Disgusting...to the point the water had a green tint and smelled like algae. Now I did water changes every week, used carbon, phosban, manually removed it, dosed gallons of Tech M, changed light bulbs every month, changed RO/DI filters monthly, etc and nothing worked
About 2 years ago I bought an LED light and noticed it started dying out. Months later I bought a new RO/DI system and eventually bought a new skimmer. Now, no bryopsis. I can't tell you what, if any, the magic bullet was but it can be beat....it just may cost a little $

If it's in small patches now I'd remove it by hand and treat the areas infected with Hydrogen Peroxide. Run GFO in a reactor and keep PO4 low before it gets established. This worked well for me during a heavy outbreak early in the hobby. Running a filter sock/pad, controlling detrius on the LR is also helpful. Good luck.

I've used phosgaurd since i set my tank up. It came in on some zoas i believe. It's spread pretty fast.

I used tech m in conjunction with manual removal and peroxide and haven't seen any since.

How long does it take with the Kent teck m?

+1 on the hydrogen peroxide. One dip and it will kill it all.

I've done a peroxide dip on my zoas to get rid of it. That didn't work and my zoas weren't to fond of it

Since i replaced my phosgaurd it looks like some of tbe byropsis is turning white. I also manually remove as much algae as i can while doing water changes . It's in my zoa frags pretty bad

How much peroxide did you use, and did you use tank water when doing the dip?

Hydrogen peroxide works very well - They sell it at CVS in a spray bottle, which is perfect.

Rather than dip, which will force the solution deep into your LR in all sorts of places you don't necessarily want it, just pull the rock out above your tank - spray the H202 directly on the patch... hold it there for 30-60 seconds and then slowly lower it back into your tank. you may want to turn your circulation down for the next half hour or so to give it a longer dwell time. It will take 2-3 days, but you will see the byropsis begin to bleach, then hermits will go after it and take the rest down. After it appears to be completely gone I recommend removing the rock and spraying once more.

If you can't pull the rock out of the tank you punch a hole in the bottom of a pill bottle. Place the mouth of the pill bottle over a patch of Bryopsis and then inject H202 into the bottle through the hole you've created.

First method is preferable, but the 2nd will work in a pinch.

When I did a peroxide dip I used 2/3 tank water to a 1/3 peroxide. Left them in there for about a minute. R_MC does spraying the live rock with peroxide harm organisms in my rock. It sounds like a good plan though

I am not able to move very many rocks in my tank due to coral growth. But the pill bottle trick sounds like it'll work
