Kevin,

Ive got a 400w mh with a 14k bulb sitting here

if you want it, your welcome to borrow it until the new setup arrives

What are the wattages on the T5s?

I think if they are in the top few inches (ie: in the 6" from top of water) they should be alright.

Chris

Each T5 is rated for 21Watts

Ohh 36" NO's.

I think you should be fine if the clams are up high.

Good luck.

Chris
