I have recently purchased a 55 gal aquarium for my first salt tank. I am doing a fish only for my first time. I have purchased the power filter and undergravel filter, heater, air pump (6 Watt). I know I need a protein skimmer, but what kind should I buy? Would an air driven skimmer work or should it be venturi? And where can I buy a wallet friendly skimmer? Also what kind of gravel/substrate should I use. Thank you in advance for the advice.
