I paid a visit to a different LFS yesterday and the guy there told me that I could change out my bulbs for coralife 50/50 bulbs. These are 18" 15W bulbs that would replace my FW bulbs. I found them online for a good bit cheaper (~$30 shipped for two). What benefit would I get by changing to these bulbs? It's a small price if I can get at least some benefit from it.
So in a nutshell, how will I benefit from changing my FW bulbs to the 50/50? Thanks
