If you are looking for a top of the line, adjustable sump solution, check out the Seamless Sump from CustomAquariums.com. The Saltwater Ambitions build has a four part solution including a skimmer tub, sock tub, baffle tub, and RODI evaporation tank.
This is one of the most customizable solutions available, and is made from a commercial grade material that won't crack, leak, or fade. Most materials (and algae!) won't stick to these pieces, so cleanup is a breeze!
Each application can be different with these sump parts because each one is drillable in a countless number of ways (although CustomAquariums.com does provide pre set dimples in their design that allow you to keep the holes you drill perfectly aligned and spaced).
The sump components will fit inside many stands as well, so while they are commercial grade and rather large, keeping them within your new or existing cabinetry is very easy.
Finally, many of the components have very nice glass lids that help control evaporation and keep unwated debris from entering your sump while giving you the ability to see inside.
This sump solution has been absolutely perfect for the Saltwater Ambtions build, and we highly recommend you check it out for your next project.
