Sapphere Posted May 5, 2021 Share Posted May 5, 2021 Is Seachem Purigen ok for a Planted Tank? Does it nullify my fertilizer? Is there anything I should know before using it on my planted tank? Link to comment Share on other sites More sharing options...
laritheloud Posted May 5, 2021 Share Posted May 5, 2021 I use Purigen instead of a carbon filter to no ill effects! I'm relatively new but haven't had an issue so far. Googling is telling me it shouldn't be an issue. Link to comment Share on other sites More sharing options...

Isaac M Posted May 5, 2021 Share Posted May 5, 2021 Hi @Sapphere, I have used Purigen on and off before in my planted aquariums for the past 3 years or so. I only used it whenever I thought the tannins were a little too high for my visual appeal. I never saw any issues with my plants either as @laritheloud mentioned. Aquarium co-op also has it in the product details that it is not known to remove aquatic fertilizers. https://www.aquariumcoop.com/collections/filter-media/products/seachem-purigen The only way I can think of it affecting your plants is that it helps remove organic waste (fish poop, decaying leaves, etc) which your plants could use as fertilizer. Usually there is plenty to go around of that stuff anyways unless your tank is not stocked very highly. 1 Link to comment Share on other sites More sharing options...
Kalita Posted May 5, 2021 Share Posted May 5, 2021 (edited) I wondered this too. From what I've gathered, it shouldn't negatively impact plants, and is a better option than activated carbon. With that, I added to my tanks a couple of weeks ago and haven't noticed any ill effects. Plants have new growth and water is clearer. I'm not sure it was necessary to add, but I did because I have quite a bit of wood. I'd be interested in hearing from others on this too. Why are you looking into adding Purigen?

MadTurtle Posted May 5, 2021 Share Posted May 5, 2021 I have been using it in my 10 gallon planted tanks and my plants (crypts,sword,java fern,and java moss) all grow just fine. I love the stuff. Link to comment Share on other sites More sharing options...
MadTurtle Posted May 5, 2021 Share Posted May 5, 2021 My main reason I use it is because it makes my water super clear. I also liked the fact that it can help control nitrates and ammonia in my tank. I have never had an issue with either one of those, so whether that helps with that or not, I couldn’t say for sure. I can say that my water always looks great.

tonyjuliano Posted May 6, 2021 Share Posted May 6, 2021 Purigen will have zero effect on inorganic nutrient levels. Link to comment Share on other sites More sharing options...
