That's partially true... Kinda sorta... SPS are filter feeders as well, but also need intense light, hence why you want clean water. LPS and softies can handle there being some dissolved nitrate or phosphate in the water, where SPS are very intolerant of anything more than minute readings of them.
As for the 9010 on a 150g, ask Illal, as if I remember correctly, that's what he ran for a while before he got his beckett skimmer.
