    Hallo everyone

    I have been struggling with a seriously bad briopsis algae problem for a year now. Believe me if I say that you have never seen anything like it before (I will upload photos later). My tank looks like one of those new Japanese style freshwater aquariums!

    I have a diy coil denitrator for NO3 control and a Phosban 150 reactor for phosphate control. My readings are all 0, but it might be the briopsis using up all the nutrients. I have tried every possible remedy, but noting seems to work. The only solution that has worked for everyone is raising Magnesium, BUT Kent Tech Magnesium had to be used, with other types of magnesium it would be a hit and run. I raised my Magnesium with a diy solution, and it worked at first, but then the briopsis grew back. I bought Kent Tech, but it seems like the briopsis won’t absorb Magnesium anymore. It’s been growing like crazy but the Magnesium won’t drop anymore.

    I wanted to convert to a ULNS for awhile, in the hope that it would mean the end of Bryopsis. When I read about the NP reducing pellets I knew that it was the answer. Then I found the following two threads on Reef Central:
    http://www.reefcentral.com/forums/showthread.php?t=1878307 and
    http://www.reefcentral.com/forums/showthread.php?t=1874551

    I decided that I am going to join the rice experiment. If you have any questions, you’ll be able to find the answers on those two threads. Here is the basic summary:

    1. Rice is a solid carbon source and has delivered the same kind of results as the NP reducing pellets.
    2. Rice will stay solid for at least a month (that is the longest the experiment has been running for).
    3. ½ a cup will work for a 50-80 gallon tank.
    4. White short grain rice seems to be the best (brown hasn’t been tested yet).
    5. There are some vitamins and phosphate in rice, but if you rinse it properly it won’t be a problem. The amount is also so small that it shouldn’t be a problem; food contains more of the stuff.
    6. I will run it in a reactor with a slight tumble.
    7. Rice is super cheap (big plus for a student like myself).
    8. This is still an experiment…

    Because I increased my feeding schedule, my nitrate started going up. At the moment it is sitting at 2. I rinsed the rice till the water was clear, then I soaked it in RO for 24 hours, then rinsed again, and now it is going into a reactor.

    I’m worried about my soft corals since I know they don’t like ULNS, but at the moment it is my only hope against the Briopsis. I know that a lot of people gave up their tanks, because of briopsis, I’m not going to be one of them.

    Will keep you up to date.

    interesting experiment.

    What I do know is Briopsis is hard grass like strands. And nothing eat them. Had some, and only method that wotks is to manually pull them off the rock. Yes, that also sounds a lot easier saying it than actually doing it.

    The softer new strands, yes sometimes fish do eat that.

    I had rocks with briopsis in a dark tank for 2 months, and they survived.... :(

    Nothing ate my briopsis. There are only 2 animals that eat briopsis, lettuce nudibranch and royal urchin, but they only work if you have very little! Briopsis can survive for very long in low light as well as low nutrients. If you manually remove it, every little piece that breaks off will start growing. Even when I removed it manually it would be back within 2 weeks, and it always comes back with a vengance!

    I hope the ULNS will kill it, since not even briopsis are supposed to grow without nutrients!

    I hope the rice will give good results as in the other experiments.

    The green at the Base of my SPS will be eaten by my slug & it's not like the other Biopsis

    best way is to manually chip roots of the byropsis off from the LR,easier than pulling it out.
    Worked for me,as scrubbing and keeping in a dark enviromnt never worked.
    not even sure the byropsis will disappear in a ULNS,they too tough

    Any rice. Long grain does break a bit at first, but not a problem. Short or med grain would be better.

    Everyone so far used white rice, but I guess brown could also work...

    I would take a rock at a time clean it as much as then put it in the sump with a sea hare slug for a few days will be nice & clean & then do the next rock & so on

    I have removed the rock and scrubbed it a couple of times... it only comes back worse!! The only thing that worked for some people was to dip the rock in acid, or boil it in a pot. It kills everything... but the briopsis is gone.

    A sea hare wont touch briopsis... its the one type of algea that it wont eat!!

    I cant put it in the dark because there are a lot of coral on the rocks, you just cant see it now... if it goes into the dark, the coral will die to!

    I also have bryopsis issues and in both my tanks I have had success with epsom salts and normal magnesium additives. It just takes longer than the Kent Tech M.

    Definately tagging and just a Question as well.

    Where does Briopsis come from, how do you get it and does everyone get it?
