Upgrade lighting OR upgrade flow??

[TRDfan]

I?m currently in a dilemma on which to upgrade this month. I recently moved up to a 65g rr tank and i have the following equipment. ML 900 and 500 pumps for circulation with a danner mag 9 return pump and quad t5ho odeyssea unit with 3 ATI and 1 giesemann bulbs.

Upgrade choice for the month is either a 6 bulb tek light with similar bulb combos OR MP10esW. which is better for coral growth/health and coloration?? lighting or circulation?? which would be my first order of business to upgrade??

What type of corals are you keeping or planning to keep?I have a 65 also and a mp10 wouldn't cut it. Would need at least two running close to max if you were keeping sps.

I currently have p/t hammer, green, purple and red mushrooms, dunkens, gsp, toadstool, zoas and palys. I recently picked up 2 different types of birdsnest frags to see if i can keep any sps. So far so good but the coloration is not the greatest.

Hence the reason i want to upgrade one or the other this month
