aldiaz33,I know this thread is a few months old, but there was a bit of misinformation here.
Def Lep, you were on the right track and Rodger Podacter totally derailed you.
The Ultima II 1000 calls for a pump that pushes between 500 and 1,000GPH @ 10' head, with 1,000GPH being ideal
Waveline DC 10000 II does ~1,000GPH @ 10' head @ 85 watts
Reeflo Barracuda does 3,225GPH @ 10' head @ 253 watts
Not sure how anyone could say that a pump that pushes over 3x the recommended flow rate is a better pump for the job.
The Waveline DC 10000II was a better fit for this filter than the Barracuda and it would have saved you about 115KWHrs of electricity every month. If you wanted to stick with a Reeflo, the ReeFlo Sword Tail Pressure Pump or the Reeflo Dart would have been a better fit, while consuming ~100 watts less.
Like it reads in Rodger's signature, people do sometimes use the search feature as he suggests, so I just wanted to clarify the misinformation.
The Barracuda would be a solid pump for the Ultima II 4000, but it's overkill for the Ultima II 1000.
As aldiaz33 suggested, too much flow through the 1000 is not good. Not due to biological reason but due to mechanical as you are experiencing. The media is designed to do both. High flow will only push the particulates back into the tank. A 2000 will allow you to trap more but it will only buy you a few days before it does the same. Trud-tles will require more mechanical than fish tanks in my opinion. Since you already have a big pump, have you considered a separate mechanical filter? In your case, I believe high flow is required to keep the tank free of excessive debris.aldiaz33,
Thanks for replying to my post. Unfortunately, I have already purchased and plumbed the Reeflo Hammerhead/Barracuda into my system. Yes. I realize now that it is WAY overkill for the system. I was in an emergency situation (our 300 gallon tank leaked and our FRT was living in a 60 gallon cube) and had never tackled a plumbing/set up project like this in the past. The positive aspect is that I have a double union ball valve plumbed into the piping system just before the pump, so I have the Reeflo gated down to about 1/2 open (to achieve the maximum allowable flow rate through the Ultima 1000 filter. I will say my Ultima 1000 filter is not keeping up with the demands of the mechanical filtration for our 600 gallon tank. In hindsight, I should have spent the $150 more at the time and gone with the Ultima 2000. The tank gets cloudy within about 4-5 days of backflushing the filter and doing a 40% water change.
