Fluval Edge &amp; Led Question I'm Going to buy a fluval edge 6gal and would like to have some input from other owners. 

I have read that the led that the tank comes with isn't sufficient for really hi-tek growing.. So I was thinking of adding a finnex 12" led just sit her right on the top. 

My question is what one should I go with.. The finnex fugeray with moonlight OR The finney fugeray planted + with moonlight led.. What's the difference beside  the planted is more expensive? but is it better or would either work for what I plan to do. 

My intentions are white sand substrate with a super thick carpet a nice hardscape driftwood rocks and some crs with neon maybe a snail Or two. And taller plants in back to cover entire rear wall. I will be doing a diy co2 or maybe paintball co2 haven't decided..opinions on both options please 

I have never run a tank under 55gal and have never had success with a carpet it's time for both lol.. 

Thanks!
