> 3 dayI ordered these late, two nights ago and they arrived today. Very pleased with how quickly I got them with the free shipping. I was very happy to pay the price on Amazon, compared to PetsMart they charge nearly $6 a filter. The only thing I dont like is, I bought the ($55) filter unit just three weeks ago for my 55 gallon fish tank and I have to put two filters in at once and they swell up when dirty. Tip: Make sure to face to the back to it doesnt jam the wheels. Looks like I will have to replace these filters every two weeks- 4 a month- very costly....so I wish they would last longer.
