Is 126watts enough for Frogspawns?

that will be plenty of light..i have frogspawn and other lps and 2 sps under 130w of pc in my 36..which i don't belive is any deeper than your 46..

 

I too was considering the k2 when looking for something for my odd shaped pentagon corner tank,didnt want a pendant. Ended up buying a 250 watt sunpod and am very happy with it axcept....would rather have something that also has actinics such as the coralife pro,150 m/h + actinics, just wouldnt fit my tank well. I dont know your tanks dimensions but something like this may work well for you. Good luck shopping, Dave

 

Thanks for the tip. I was originally planning to do actinic supplemental lighting, but I'd like to keep my tank top as simple and open as possible
