Purigen Organic Ultimate Filtration Resin 100ml (3 Pack) - Aquarium Fish Tank Filter Media for Freshwater & Saltwater with 10ct pet Wipes

Always works great

Awesome stuff, I use it in three tanks and change it out at about six weeks with a moderate fish load.

Works really well. A bit pricey but it cleans water well.

Purigen was the filter I'd been looking for to clear the water in my fish tanks! I had tried different water treatments and changed my other filter cartridge weekly and nothing cleared my aquarium water better than Purigen. I took out the filter cartridge that was specific to the filter and put the Purigen pouch into the filter cartridge area. Within an hour, the water color went from yellowish to a foggy white. By 24 hours after, the fogginess cleared up and the water was crystal clear. This filter is reusable but you do have bleach and water conditioner to recharge the pouch. There are YouTube videos on how to recharge the pouch. Worth it in the end. I highly recommend Purigen!

Seachem is always a little more price wise than the competition, but they make a high quality product you can trust to deliver as promised.

It works great just might be the reason why my Phosphates were not hold so I removed to get nutrient balance back.

Works great.

This did exactly what it said it would do, even from others that have raved that it gives Crystal clear water and it does. If you think your water is clear try this and you are going to be surprised of how clear your water can actually be. Worth the price absolutely works and I love it!

Keeps aquarium crystal clear
