Review on COODIA Internal Aquarium Submersible Disinfection by Pamela Ervin

26 gallon (24 x 20 x 14) front Fluval tank included. I used live active gravel in a well planted tank and raced it from mid August to early October before adding the fish. There are two pieces of wood between the stones. Designed as a public aquarium for Apistogramma Boreli Opal, they have been difficult to find. My aquarium will soon be complete when I add a trio of these: 6 Celebes Rainbowfish, a pair of Varneri Rainbowfish, a pair of Flagfish, 4 juvenile longfin pygmy catfish and 3 stunning juvenile discus fish. This aquarium is crowded to be sure. I had an issue with muddy water long before Rainbow and Flagfish were added. Then the algae bloom seemed to start. I've tried weekly 40% water changes, API Clear and the algae only got worse. Concerned about all the chemicals I did another water change and added this internal COODIA Green Water Killer Filter. In three days everything became absolutely clear. After two more days of running I turned it off due to the current. After 4 days everything is still clear. Check it out below. The COODIA UV filter is on the left behind the large rose quartz.
