I didn't even notice the fact that he mentioned "freshwater". A lack of sleep last night has led me to not be firing on all cylinders today. Heck, I didn't even know that Ecotech had a freshwater specific version but then again, I only pay attention to the salt water stuff anyway. If that's the case and this is a fresh water specific light, then the XR15 would probably work fine and certainly better than a reef version. Most of the fresh water specific lighting is well suited for planted tanks and typically provides a "daylight" spectrum that would be consusive to decent macro growth. Still, it would have to be a steal for it to be worthwhile in my opinion simply because there are lots of very inexpensive lights that will grow macro very well.
