I’ve used Fluval ClearMax in my 100-liter freshwater tank for three months. The water clarity improved noticeably, and I no longer have the strong fish odour. My betta fish seems more active and healthy. Easy to add and works well with my Fluval 206 filter.

The product arrived quickly and the instructions were clear. After using it once, my tank water became noticeably clearer. I’ve seen less algae growth too. Works well with my saltwater setup and the filter compatibility list matches my model.

Great product for reducing nitrates. I’ve used it twice in my 200-liter tank and the water remains crystal clear. My plants are thriving and the fish don’t seem stressed. No issues with the resin or installation.
