Introducing a "NEW CHANNEL" and setting up a New Fluval Flex 15Gallon tank.. DIY - optimizing and modifying the filter to improve overall filtration in the aquarium.. This should improve the water circulation and filtration flow by 100%. 
The way the tank filter is made the water comes in through the two intakes of the filter and just flows across the supplied filter media sponge... Water will always take the path of least resistance, so you will not get a good filtration with this design.I don't even see how this would even utilize the supplied small amount of biological media..
 In this video I will modify the filter forcing the water to flow into the filter at the top intake  flowing over ceramic rings, filter floss, Filter Pads and Bio Balls. Then it will flow down towards the bottom fill over into the second chamber exiting at the top dumping into the 3rd chamber where the Aquarium Heater, UV light and Pump are stored. Then sending the water back into the tank filtered..Before the modification the water entered top and bottom and flowed across the filter.  I also add 2 large bags of Bio Balls , 1 lb of ceramic Rings , 1 lb of ceramic blocks(1 1/8" X 4" times 11)  plus filter floss and filter pads  to aid in cleaning the tank.. VS the 8-10 little ceramic rings a hand full of carbon and a filter that was supplied, I probably have increased the filtration by 4 or 5 hundred + percent.
