Trouble Priming then it humms!!

Date: May 16, 2006

"After installing the tubing on the tank and suction lines, I found allowing a powerhead within the tank to blow into the open end of the suction line, removing the screen obviously, it primes almost instantly!! I have a 125gal and own two cascade 1000s for it. Literally scrubs the water!"

great buy

Date: October 6, 2009

"just bought the pen tax 700 . over all its a great filter for the price. (i have read reviews saying its hard to prime this filter)not true ,after putting everything togather fill your canister with water to proper level like inst. say then fill the tubes with water with valves shut.conect tubes to filter then open . you still have to pump about 10 times but not nearly as much if you dont do it the way i sugest above. 10X with tubes full of water-30-50 times with no water in tubes."

Under Rated

Date: September 21, 2009

"Bought the 1000 for a 75gal tank acouple days ago and works perfectly. No leaks, cracks, or noise coming from this filter. I did prime it about 10 times becuase of other reviews, however, it took a total of 15 mins for it to get all the air bubbles out of the lines. i would definetly recommend and plan on buying another one for my 55gal."

Poor Value

Date: September 16, 2009

"I purchased this to give my fish the cleanest healthiest home possible.
I can honestly say it has made no difference, My whisper 900 made more difference than this did.
The set up was easy enough using logic instead of the very useless directions.It took about an hour for all the air pockets to be purged and after that fairly quiet.
Overall I would say to avoid this series all together.
There is so much bypass around the filter baskets it makes this filter useless. They should investigate putting seals around the outer edge of the baskets."
