Bryopsis

[sicksnoopy71]

This stuff is ******* me off. So I have a 50gal reef, straight killin it. But my refuge is quite new. I finally decided to go to refuge sand and mud but the mix I did was pool sand and mud. I heard that it was ok, however, since first using it I have noticed every tank I start or use it in develops phosphates constantly. Obviously, reason why I get the bryopsis growth in my fuge over night. BUT... Thats not my problematic thought. When I cut light out over night some night the bryopsis will starve out and die, yet when I leave light on over night it comes back. I am constantly doing this night in two nights out, just straight randomly. What is wrong? Should I pull the sand? Or should I change the light bulb. I believe the light bulb is old as a mummy but I am just still skeptical about the sand too. At the same time I have calurpa growing in sand bed. Will it live without sand and mud? Or will I have to forefit everything and just go rocks?

Try increasing your magnesium that while melt it.

The only Magnesium that seems to work on killing this algae is the Kent Tech-M.
Get a new fuge light.
As for you substrate in your fuge, go with one or the other but I wouldn't do both. The calupra will adhere to rock rubble also.

There are two ways that worked for me.

1. Increase your Mg up to about 1500 maybe more which should kill it off but is safe for tank mates including coral.

2. take a bag & cover the area the tie with a rubber band then inject hydrogen peroxide (yes the stuff used to bleach your hair) after a day or so you'll see the bryopsis fall off the rock & into the bag them remove the bag with all the bryopsis in it.

I thought pool sand has silica in it which causes the algea

Pool sand can be made of silica, which can feed diatoms. It does not feed algae.

My mag is already 1340 or 1320 or so.

You know. Maybe I'll have a closer look at it today. Sounds like it may just be the most purple redish diatoms I've ever seen. However, that still means I may have to pull the sand since the silicate will continue the diatoms process? It does not seem to cycle away but just spread.

I just went through the same crap and tried some different things and nothing worked. FInally went with tech-m and it worked great.
