Diablo DC 5500s Skimmer Pump Replaced with RODC 3500s - Performance woes?

richfavinger · 09/16/2014, 09:41 AM

A few weeks ago I had discovered that my Diablo DC 5500s Skimmer Pump (black) just up and DIED… No apparent cause. It had been running on my Diablo 200 INT skimmer for about 6 months. Flawless, and pulling out the nasty daily.

I contacted CoralVue support and they did take care of me. But strangely, they informed me that the replacement for this skimmer was now the RODC 3500s Skimmer Pump (white). Puzzled I questioned why. - It’s 1200lph vs 2000lph … they assured me that it is the replacement and that it’s more efficient then my old DC 5500s. So under warranty they sent the replacement at no cost.

First things apparent that it mounts reverse to the old pump, so I had to move a few things around the sump… Second thing is that I now have to dial in my skimmers gate valve about half-way (with the DC 5500s it was wide open), third… I raised my sump level from 6.5” to 8”… and it still doesn’t seem like it’s producing nearly as much nasty as it did… The RODC 3500s is also running full speed on level 5, the DC 5500s typically ran well at level 4… (of 5)…

Did CoralVue neuter my skimmer? I’m not sure if the tank is simply running cleaner (it is light-med stocked) or my skimmers manhood has been taken. But, I don’t seem to get near as much nasty after running for 2-3 weeks now as I use to. - Before I was cleaning the cup every 3-4 days… Now we are not even close!

They should update their site too as it still calls out the 5500

Oh, I'm aware of the old specs mcgyvr...

Noted that the replacement Elite 200INT 8in Super Cone Protein Skimmer calls for the 3500s

And the Elite 220INT 9in Super Cone Protein Skimmer uses the 5500s for one more inch...

Really a disservice to clients if that is the case...
