higher Mg and lobophora variagata?


New member
I've been dealing with lobophora for a while now. Heard that emerald crabs and long-spine urchins could be hit or miss (mine were miss), and I don't have the room for a Naso tang.

I've been reading around about how elevating Mg levels by using Tech M combats bryopsis, but could it work for lobophora? It's not to the point where everything is covered with it, but I'd still prefer not having it.

Given that no one really knows what it is in the Tech M that actually inhibits the briopsis growth (it's pretty well assumed it's not the magnesium, but some impurtiy), I doubt anyone could reliably answer your question. You could certainly give it a try and post your results. I don't believe there are any significant hazards to raising your magnesium levels to the prescribed amount (1500ppm if I remember correctly).
