Between the two skimmers—the
Tunze Comline DOC 9004 and the
CAD Lights PLS-50 Elite II—both are solid options, but I’d lean toward the
Tunze for a few reasons.
It’s super quiet, easy to use, and does a great job for tanks up to around 65 gallons. It’s also widely available—
Amazon or through us, we have it in stock.
The
CAD Lights PLS-50 Elite II is a cool little skimmer with a unique, space-saving design and great performance for its size. But availability seems to be an issue right now. I couldn’t find it in stock anywhere, though it used to be sold through places like Mode Aquariums and Dream Fish Tanks.
So unless you’re set on that pipeless design, I’d go with the Tunze—it’s reliable, easy to find, and does the job well.
We sell them here if you need it:
