GSP growth?

hey,

i have about three different colonies of star poylps. weirdest thing; they grow and spread but hardly open. when they are open they are certainly not fully extended. has anyone ever experianced this? i don't even understand where they're getting the energy in order to spread.

what could effect the extension on GSP? My water quality is good;
NO3=0, PO2=0, 250w 10k XM's.

I had mine under 250w MH, and mine didnt expand much, or grow. Now I moved them into another tank with T5's and they are growing like weeds. So I think you may need to lower them, or move them into a more shaded area.

I have had just the opposite. I kept mine under 400 watt halides, very close to the light and they grew fast and were very long and extended. They also recieved a good amount of flow.

Do yours get much flow?

thanks for the responses!

I'll definitely try lowering them. I also have a 20l with a 15k 250w and the light is high above the water; probably 15" or so. The GSP are extended fully, I just never made the connection.

I don't think i have a water quality issue, i keep healthy and growing sps in the tank.

Oh, sorry.
I would say that the area that houses the gsp is more on the lower end of the spectrum, i do have a piece of it I can move. I'll try putting it in a higher flow area and what happens.

I would try more flow before decreasing light.

Mine are blasted with flow and they grow like weeds even though they are not in full light.

High flow makes mine grow like crazy with long polyp extension.
