Lights and power heads are set “very low”. My 6 foot SPS tank has six power heads. The surface flow looks like a hot tub!
If you want to grow acros, you have to do it right. The acros are your focus.
Yes but I’m saying if his frags died shortly after without growing, then I wouldn’t point to flow right away.
Ya he needs flow if he wants to have sps and colonies but my frag tank doesn’t even have a power head, just some basic return flow and sps frags are doing well from near death shipping experience. I’m sure they wouldn’t once they actually branch out but for right now they are not big enough to need much.
