I want to get a protein skimmer hob for my 30 gallon but so many choices.Is there a good one that's not real expensive but not cheaply made?I have a octopus 100 for years in my 75 and it's awesome.
ESHOPPS PSK75H is a solid performer....I have 2 that I used (now sitting in garage as back-ups). SUPER quite pump.....you can find at a great price on the forums. ...and this one is a great HOB skimmer. https://www.coralvue.com/icecap-k3-200-hob-protein-skimmer-openbox
I have the bigger on on my tank now (K3-250)
Note: Albeit they are open box, these have never touched water.
