Best Biopellet reactor

[banditpowdercoat]

Is the cad lights reactor good? I'm thinking I need a new one. Have 2 TLF reactors in series off my return pump, but not quite enough flow once I split it, and it takes and dumps from my main sump. My Skimmer is in a 2nd sump(Rubbermaid) beside tank. I might be able to fit the CL reactor in the rubbermade. But want to know if it's worth it? I do get clumping after a while in the TLF reactors. Tank sitters never shake them and I'm gone 3wks outa 6
