Filtration wise I think you'll be fine.You really don't want the tank going over the 74 degrees if you can help it. 74 is the upper end of their temperature limits in a home aquarium. Running it that high leaves you zero room for a temperature spike. High temperatures have a nasty habit of sparking bacterial infections in seahorses.
Don't be afraid to let it go below 72 degrees either, none of my seahorse tanks have heaters and they will drop as low as 68 in the winter time with no ill effects to the seahorses.
If you feel that you do have to run a heater, then please put a guard over it. Seahorses will hitch onto anything and an uncovered heater can cause a nasty burn.
Also if you found on Seahorse.org that it said 75 was the optimal temperature, please provide a link to that information. Last time I looked, they were recommending 72-74 for tropical species.
