Review on Fluval Flex Aquarium: 57L, 15gal Capacity - Hagen HG (White) by Jennifer Lyon

This is a really nice 15 gallon aquarium with great features. I have to say that I was completely surprised at how good the filtration system is. I used to have to clean the aquarium every week and run the filter system every two to three days. With this tank, the water stays crystal clear for weeks. I flush the filter system every 10 days even though the water is clean. At first I thought maybe I paid too much for this aquarium, but now I don't regret the purchase at all. About every 4-6 weeks I use a siphon to clean some of the food that has settled in the filter. area and replace one-third of the reservoir with fresh water. Gets a little cloudy after collection, but the filter will clean it out in about a day and it's crystal clear again. I highly recommend this tank.
