Hey guys im thinking about starting a saltwater tank, ive had numerous freshwater tanks before but now i want to try saltwater, i kno what it intales ive done research and even bought books on it, What i have is a 30 gallon long tank with stand and everything, i kno that 30 gal isnt the recomended minimum but its do-able, what im asking is i see protein skimmers going for big bucks online, is it one of those pieces of eqiupment that u really need to pay for quality? Or can i get a cheaper one and itll do the job?
