Lower light (not in the shade) with Low flow for the blasto. The flowerpot can handle high flow and will adjust to whatever you put it in. The higher the flow you go the less it'll extend out that's all. I don't have par levels but for some sort of reference, my red flowerpot is in my 220g SPS tank sitting on the sand bed 30in below my 60" six bulb ATI Sunpower.
