Need water parameters.

this is what my parameters are:
sg=1.026
ph=8.2
nitrate=0
nitrite=0
phos=0
calcium=440
dkh=9
ammonia=0

Honestly, softies like GSP just don't do well in low nutrient/nitrate/phosphate tanks. Mine have always done best in dirty tanks. I tried to grow some GSP on a "rock island" in my 120 gal SPS reef that had parameters similar to yours. I thought I had actually killed the stuff. Took that same rock and moved it into a 57 gal mixed reef with elevated nitrates/phosphates, and it spread like crazy.
As a longtime softy keeper, this has just been my experience. As always, opinions may vary. :wink:

Algae is very bad for GSP it prevents them from coming out of their tube.
