Seahorse Switched

I have noticed people on this forum getting seahorses and i have finally seen one in a LFS and now that got me wanting one, haha great. For those who seen my new tank under "tanners Christmas tank" i am using that new setup, but changed. I have took off the filter and added a new one, it is practically a HOB refugium. It has three sections, and a sponge cover over the intake, then goes through 3 different compartments - Active carbon, and zoelite rock then goes to a filter sponge the to the largest compartment - like rock, deep sand, and algae, then back into the tank. There is also a heater in the 1st compartment.

The seahorses i plan on getting are dwarf seahorses, but before i get them, i am going to buy rotiferes for the refugium and tank. I do know that they need live foods so i am getting rotifers, and buying a  8 oz container of artemia eggs at 90% and will hatch them daily and feed them to the horses while they are babys still so they have a high nutritional value. I already have the hatchery set up for them. I have done a TON of research on the seahorses and brine shrimp hatchery trying to see the best way i could go about. When i get the horses i am getting them from seahorseworld.com and ordering 2 males and 2  females.

Note- I also took out the torch and frog spawns out of the tank to eliminate the horses getting stung or burned. the tank is 4 gallon rimless. I have put in a couple fake plants that are tall for the horses to grab on to. The tank also has low flow and the only corals i have in there are zoas and a couple palys, and fungias.

Does everything sound okay so far? Do you think this set up would work?
I really need to get pictures up soon, and i will soon as i get home. Thanks, let me know how this setup sounds and what you would do differently.

I am still going to wait for about a month before i get the actuall seahorses so i can populate my tank and refugium with rotifers and copeods and stuff adn to make sure i have everything i need before hand.
