For a seahorse nursery tank, my understanding is that it is best to have only an airstone for aeration and water movement. It will mean consistently changing the water, though this would only be until the fry are big enough to manage in a filtered tank.
When you cover a filter intake it does not stop the intake pressure. Covering the intake only keeps larger things from being sucked OUT of the tank.
I don't know that you could have a filter powerful enough to do any good that would not also trap the fry, as well as their food, against any sort of covering.
I use one of those huge black sponge intake covers for my dwarf tank, and I use Aquaclear 110 on my tanks. The pony babies don't have any problem zipping around, however, pony fry(flies
) are larger that horse fry(flies
), so I do not know if the horse fry would be strong enough to swim against the intake even with a flow cover.
