This Whisper Triad Foam Retro Fit Kit
This add-on kit work great and will help your Whisper Bio-Bags do double duty, by enhancing and boosting the biological filtration of your aquariums water quality. This works to promote the good nullifying bacteria by doubling it, and it helps to polish the water a second time before it goes back into your tank. With healthy water you get a healthy tank & healthy fish, which means less time to worring about a sick tank = Priceless I Say...
