I was just curious whats considered to be low light and a medium flow and so in? I have a JBJ 28gal nano with LEDs. The two stock pumps and one 240gph Koralia powerhead. Green hairy mushrooms for example do I want them on the bottom with a powerhead not hitting them but to where they still move from the current? Is that low light medium flow? I have some red mushrooms at the top of my rock work behind the return pump no movement is that considered High light low flow?
