Lee's Triple-Flow Corner Filter, Large

There's a local fish shop in Lewiston, Maine I visit about every 2-3 weeks or so. The owner is a gentleman I'd guess to be about 70 years old who says he's been in the business for 40 years. I'd estimate he's got well over 100 tanks running in his store. Compared to the other pet stores in the area (Petco & Petsmart types), his tanks are crystal clear. Yesterday, I stopped by and struck up a conversation with him. He started asking questions about my tank (75 gallon freshwater) and my filtration system. When I told him I was running an Emperor 400 HOB filter, he promptly told me it was no good. I asked if I should go with a canister filter. He told me those are "crap". He recommended that I install a couple large Lee's corner filters. He pointed out that he uses them in all his tanks, and credits the filters with keeping the tanks so clear. He claimed that he's sold 15,000 of them during his career. He emphasized how inexpensive they are to buy and operate, and that they require very little maintenance. He suggested changing out the carbon and polyester fiber about every 6 months...but also stated that he's got filters he hasn't touched in 3 years. For about $30, he set me up with 2 large filters, and enough carbon and polyester fiber to last at least a few years.

On the way home, I got to thinking about my little aging air pump, so I stopped at Walmart and picked up a more powerful Tetra Whisper Air Pump with dual air outlets for about $20. Less than an hour after I got home, both filters were up and running. Like some of the other reviewers stated, the quality of the plastic is disappointing...I'm giving this item a 4 star rating (rather than 5 stars) because of this fact. The unit seems quite fragile and I imagine it wouldn't take much to break it. However, I'm already liking these filters. I like the fact that they are clear, enabling you to see them at work. When I got up the next morning (about 12 hours after installation) I could see a noticeable difference in the water clarity.

For me, the true test will be how they perform over time. But for now, I'm impressed.

This filter does the job as expected. I am not so found of the attachable base on the bottom. It make the filter sit crooked in my gravel. I also would change the air tube. I like using an aeration stone, added oxygen in tank, but the little tabs that hold the tubing in place are fragile. The sloping lid makes it hard to keep the poly filter material in place while placing the filter into the tank. Otherwise, this is the kind of filter I was looking for to place in my 10 gallon tank.

works well, very economical. After replacing my third h.o.b. filter in the last 8 mos. I wanted something reliable. I had to run a small power head to help with flow and thwart algae growth that had increased due to the poor hob filter performance.
