Skimmer or no Skimmer??

[Key Equine]

Hello everyone,

I am starting up a 45 gallon SW tank which is going to be for seahorses, once I can find a captive bred supplier I trust...

I am planning to have a cleanup crew of snails, hermit crabs, and cleaner shrimp, and eventually four to six seahorses. I have an external filter as well as lots of live rock. I am wondering everyone's opinion on whether I need a protein skimmer or not. If so, what type do you recommend? Noise is a major factor for me since the tank is in our main living space.

Thank you!
