Package Size: 2″x3″, since the balls vary in size considerably from batch to batch and even within a batch. An order is now a full bag, the number of balls may vary.
Filter Starter Balls kick start your filter by releasing a steady stream of beneficial bacteria that goes to work consuming ammonia and nitrite. These gel balls were originally designed for use in moving bed filters, but are really effective in all styles of filters.
They can be used to start up a new filter or to help keep the levels of ammonia and nitrite under control in heavily loaded tanks. We recommend a quarter bag of of balls for 40 gallons of water. They are designed for freshwater and may not be effective in marine systems.
When using the Filter Starter Balls, I’d suggest you place under the media so they won’t float away and leave the filter. If you are not confident you can retain the Balls in the filter, then I’d suggest you place them in a media bag.
