Is GSP a big nutrient sink?

I'm gradually eliminating some less desirable stuff from my system, and my big (12" x 8") GSP island is next on the chopping block.

The last big removal I made was a monster 10" tall xenia colony, which is known to suck up nutrients. Once it was gone, I ended up with a gradual increase of nitrate and phosphate that I'm getting under control by extending my refugium lighting period.

Is GSP as much of a nutrient sink as the xenia? Am I in for another bump?

There are different kinds of GSP, some very explosive in growth and some not. I have found the explosive one tends to be pretty effective at absorbing some of the nutrients once the colony gets large enough. I have found that once the growth is impaired due to physical boundaries that the coral cannot grow past, it does become less effective at absorbing those nutrients. All of this is based on my observation and there were other variables at play that could contribute to this.

Thanks, unfortunately mine has decided it doesn't want to stop at the rock's edge and has started creeping across the sand.

I think I'll just have to pull it out and deal with whatever the aftermath is later.
