Our premium pads do a wonderful job of keeping aquarium water crystal clear but it may not be the best option with your Aquaclear 50. The Aquaclear sponge does remove particles from the water but its other function is to grow beneficial bacteria which breaks down fish waste, excess fish food etc. These bacteria allow you fish to live in an aquarium and not die in their own waste.

The sponge can be rinsed out every week or 2 in de-chlorinated or old tank water to keep good bacteria alive. Then it can be placed back in your filter. Whereas our dual density premium pads can be rinsed and reused they are not typically used as the biological part of the filter. They are normally used as a prefilter or mechanical filter with their job being to remove large to fine particles from the water. Even though I love this product and it does an amazing job, in your case if your Aquaclear 50 is doing the job I would probably not change it.
