Halimeda and other macro algae in DSB

[Pszemol]

I am a little bit confused...

My future 10g refugium with DSB is still offline but
I have a lot of macroalgae in it and 24 nassarius snails.
Snails seem to be hungry so I feed them once per couple
days with fish flakes. Also, to feed macroalgae I use
liquid fertilizer designed for algae aquacultures
in small doses (1/2 normal dose)...

I guess my DSB started working with full speed because
I cannot measure NO3 at all and I have big die off in
Halimeda plant. It is almost comletely bleached white.
Salnity is 1.024, Ca=400, Amonia, NO2, NO3 - zero...
Light period is about 10h a day, manualy controlled.

Is it possible other macro algae and DSB outcompete
Halimeda in the race for food or denitrification?
What are common reasons for Halimeda plant bleaching?

sounds like it went "sexual on you. this is common with macro algae and can
be prevented by not stressing the algae. keeping your lights on 24/7 is one
way as well as not allowing your algae to become crowded.

I dont think that halimeda "goes sexual" like caulerpa does.

Not sure if it is sexual or asexual, but that is the reproductive phase
of the halimeda life cycle. It will grow back before long. Its not the
same type of event as caulerpa going sexual, as there is a detectable
nitrate rise, it isn't caused by overcrowding or neglect, and it isn't
spewing toxins into the water.

After it regrows, you will likely have several plants that will all go
through this phase at different times. once you get enough plants you
won't even notice anymore.

hi.
They do, just not as often, and not as nasty.

well like matthew pointed out, its a little different form of "going sexual"
but its normaly caused by the same reasons................stress from
overcrowding and the such. it will grow back unlike caulerpa which IME is
gone when it goes.
