API 441D First Impressions

Thank goodness!

Fish possess an antioxidant defense system to reduce the negative effects of ROS. I will purchase this again when needed. We've got 2 in ours even though the package says to only use one. I use water from the tank, but you can use treated water. I have done this a several times with great results. No observable signs of stress in the fish. I am able to use each cartridge for about 5 weeks, before it needs to be replaced.

API 441D Final Thoughts

Works like a charm.

I have used marine land bio-wheel pump and filters for the past 20 yrs. I have never had one tear or fall apart under any circumstances. Don't claim to be an expert, but I've never heard of that. Great price for filters that are ready to go, with no assembly required. When they disinfect a repair site, they are normally only using chlorine. This piping and some electrical tape made it quiet again. But intjink it has alot more to do with the pump rather than the tube.

Overall Score
4.6
