Low Nutrient Or High Nutrient

Any idea what your par would be?

Man I have no idea, Im runing 32 aquastyle online leds. 16 RB, 16 10k.
Is there a par meter?

I keep sps, lps and even a few softies. 

As unibob said, I keep undetectable nutrients via pellets and gfo, and do target/spot feedings for the lps.  Last night was feeding night, I turned off the pumps, put some pellets in one corner (to distract any fish that woke up and the sniffer on the shrimp).  Then dropped a soup of mysis, micro pellets and reef roids onto the top/mouth whatever of each lps.  Things like candycane closes right away.  Acans really take their time, and chalice...well chalice is the slowest eating coral on the planet.  Once the chalice has got a few globs down I fire up the pumps and go to sleep.  Works well, but if the lps aren't fed they don't grow. 

The other key I find for a low nutrient system is very frequent water changes.  Who knows maybe it's the carbon or something, but the sps really takes off when I'm doing a LOT of water changes. 

I'm still not sure how GFO could kill sps.  Was it regular GFO or was it aluminum oxide based?

I notice a growth spurt in my sps after a water change to. They seem to love it

I think you got your answer already. +1 for everyone on here. High/low nutrien and gfo will not kill your corals. Alway  test your water before changing anything . running carbon/gfo is a must IMO. I would stay away from bio pellet if u don't have any experience with it. Like saltyC. Mention earlier you won't notice any different  in the first 3-4 months and if u run it too fast thing can get real bad. Good luck.
