I have an IM25 lagoon that I would like to run 4 t5 and 1 reefbrite xho strips on. Should I use the 24" strip or would the 15" be enough? All I want out of this led is some actinic supplement and some shimmer. If someone has a different led suggestion please let me know. I am personally done with using led as my main light source so we are just discussing led as a supplement/shimmer light. Appreciate the responses or suggestions
