haha lol, your tank is cleaner than mine...thats for sure..just add when you're confident and have deep pockets. Sps corals require some additional work on your part like dosing unless u are willing to invest in a dosing pump...i think your light may be sufficient but in case it isnt enuf, u may want to upgrade to par38, lumenaqua max 200...also if u're water movement isnt enuf, u can just add those cheap n tiny powerhead...something along the line of tunze mini universal pump, dymax 200
