Hello guys I have zero idea how a skimmer works or if I even need a skimmer, I’m setting a 13.5 gallon tank (the evo) and I got this fluval skimmer with it(I don’t even know what it does) do I need to use it? What’s the purpose of a skimmer? I briefly tried to read on it and is it suppose to replace you doing water changes? I was intending to do water changes as that’s what I’m use to with freshwater but just curious. if the fluval skimmer is bad as ive briefly read it also can be what would be an alternative if a skimmer is necessary? Would I want to do both water changes and use the skimmer?
if anyone can help answer that would be wonderful!
