Review on 🐠 High-Quality Penn-Plax Clear-Free UGF Aquarium Filter – Freshwater & Saltwater Safe – Ideal for 15 to 20 Gallon Tanks by Dawn Rodrigues

I decided after a few years my rescued goldfish feeder needed a new aquarium. I went the old fashioned route and used a rock chip filter along with a sponge filter. I ordered this for a 20 gallon aquarium measuring approximately 12x24. The combined panels were too wide and I had to cut about 1/2 inch of material to fit. My tank is custom sized so I had to make a small modification. The tank looks cleaner than ever, I don't think I'll ever go back to expensive filters. My fish have never been happier.
