I recently bought a 40gal breeder and a 29 gallon tank since well I wanted to use a 20 long however I noticed the 29 has same length/width so it works. I’m going to drill the 40 gal and use the 29 as a sump, it’s mostly to ensure I don’t flood the house and more water is a good thing. Anyway what is a good affordable protein skimmer? I may end up getting a few small messy fish that could impact bioload
