Skimmer question

[Westoncase]

I’i don’t have a skimmer yet for my 40breeder, is this worth the 100 bucks?

I

also are they loud? Noise pollution is a deal breaker

They are fairly noisy for a hob style but not annoying, the Reef Octopus BH 90 would be a better option and I think new they are only around $200
