Seahorse Tank

[Key Equine]

Hello again,
I am using the Rena xp2 that I had already from my FW tank, in it I have mostly live rock rubble, then a carbon insert. I have heard both sides of the filter in SW debate, but I had it already so wanted to make use of it. So far things are going fine without the skimmer, but the tank is still really new of course. I do want to get one in a few months time.
I have been told that you can get away without a skimmer for a seahorse, and I feed my seahorse very carefully at a feeding station, and then if anything gets away from him it is quickly picked up by the cleaning crew, so it's staying pretty clean...
