Yup. Should be fine. Make sure you target feed the seahorses and what I do is set up a feeding station. Usually I use a "bush" of red halimenia. I shoot the mysis in there & the seahorses pick them off the "branches." It keeps the food a little off the bottom & easier for them to see. It also makes it easier for you to make sure they're eating everything or at least most of it.
Mine love to hang off a couple of small frags of corky finger gorgonia and a "stick" of LR that's stuck into the substrate. PE mysis is a bit big & messy compared to feeding them Hikari mysis. Mine love both but big clouds of shrimps guts squirt out their gill openings when they suck up PE mysis.
Seahorses actually prefer lower lighting levels so 96w PC might be too bright. I have a 10000k 96w over my 33g & they tend to hide in my cave when not out feeding or hunting live mysis & pods. Remember, seahorses need multiple small feedings a day, not one big one. Ideally, they should be in a mature tank that's full of pods & live mysis.
