I would look into getting a HOB protein skimmer. And if your looking int sea horses that means no fish except maybe a neon goby or two. Personally I would do a lot more research first, You can easily accidentally throw a lot of money.
Would a 30g with (1) AC 110 diy fuge, (2) AC 50 power head, and (3) HO protein skimmer make a for a good, stable tank?
Also, anyone care to make a recommendation for a skimmer brand I should look at?
Thanks!
