I recently got a new Aqua-tech 20-40 gallon water filter, now after less then a week the water looks real mirky it does not smell but it kinda looks like its going through the blooming stage (though the last time that happened it lasted a day).
Before with the old filter the tank would just get really covered with algae so i knew when to clean it. but now, the only place the algae grows is on the replace-able filter cartridges. The filter's say there good for 2-4 weeks.
