Hydras 52 HD for 18 gallons cylinder tank

[Leez]

I have 3 hydras 52 HD left from my old tank, thinking of using all 3 of them for my new setup. Do you guys think 3 is overkill ?

All 3 on that tank, I would say yes. How are you planning to hang them?

well, maybe one parallel with the tank and the other two has a 30 degree inclined on both sides to prevent shadowing ?

Try to mount them as a triangle

interesting concept. If you have the real estate you can try it but FYI I know someone with a full blown SPS system that runs 3 HD's over his deep 220.
