Buy Now!! Don't Wait. by BuzzStPoint11/07/2012
Can't believe I waited so long to buy these. I bought 2 of them, one to fill with charcoal and one I filled with poly fiber. No more of the expensive cartridges.
Awesome Product by ItchyNissan from Federal way wa01/07/2012
I purchased this product so I would not have to buy the ones that are not refillable. I purchased 2 because I noticed 2 slots in the penguin 200 filter. The filter cartridge is great. It's sturdy, holds a lot of media and fits perfectly. The price was awesome and the shipping was really fast. I purchased them and got them on the 2nd or 3rd day. I can't remember but I think it was the second day. Great company to buy from. I was satisfied and you will be to.
amazing what these take out of water by aj10/05/2011
I am always grossed out at how dirty these filters get in less that 1 week. I have 2 big goldfish and two catfish and the filter is plugged in short time( I do NOT overfeed) and I change water every 2.5 wks. These definetly clean well.
