Green Button Polyp Question

you rotten jammy sod. I cannot for the live of me get these to take on in my
tank. I have 30kg of live rock in a 40G tank with 4 powerheads for flow, 2x
actinic 36" tubes (marine blue) and a 150W MH. my sump has three chambers
of media, one with calerpa and a prizm skimmer. nitrates are a bit hard to
control but the other parameters are all within normal limits and the green
buttons refuse to open or even die off. they remain permanently closed.
What am I doing wrong. my tank dimensions are 36"x18"x15" with a
36"x15"x12" sump and a Rio 1700 return pump.
I am currently awaiting the arrival of a turboflotor skimmer to clear up the
debris and OR6500 return pump.

HELP.

30kg of rock? in a 40g tank? Is there ROOM? Thats'....almost 70lbs!
Typo?


Lose the filtration media, let the Live Rock do the work. Getting a
better skimmer will help big-time. I have a 75 gallon with 70lbs LR,
and so little nitrates that macroalgae won't grow. I'm probably
overskimming with the Euroreef, I've been dialing it down the last
couple days.

The light may be too intense, 150W of Halide plus the actinics may be
too much for a 40g tank, but I'll let a light expert comment more on
that.

And tell this ignorant American wtf a 'jammy sod' is?

problem is that it fills the most of the tank with very little room for
anything else. I'm seriously thinking of moving some into the sump and
leaving a bare minimum in the tank. this will allow room for corals and a
lot of flow.
