Chamberless sumps

[sphelps]

you don't baffles at all.



It all comes down to what you want, not sure it's a new trend but yes most new skimmers don't release bubbles so bubble traps serve less of a purpose now depending on what skimmer model you use. However the rest is really personal choice, baffles can still be used to direct flow through filter media or socks and chambers still serve a purpose to separate equipment and serve and boundaries for refugiums and such.
