Tannin Aquatics Premium Dried Magnolia Leaves (Package of 10 leaves)

The leaves of the Magnolia tree are distinctive, attractive, and very useful for aquarium purposes., both decorative, and as a supplemental food source/biofilm substrate. They can vary widely in color, including oranges and browns, which makes them particularly attractive for a mixed leaf litter bed! We've been playing with them in our own systems for some time, and we we so thrilled with them, we figured that it was about time we made them available for sale. Besides, some of you were getting pretty jealous of our litter bed tank on Instagram and Facebook! 

Magnolia leaves are super variable in appearance, as indicated above. There are over 50 cultivars. Magnolia grandiflora (the one we typically offer) is quite beautiful. Ours are harvested just for us by a trusted North American supplier, and they've been sustainably sourced, and are free from pesticides, herbicides, and pollution.

Our Magnolia leaves are harvested after they have naturally fallen, which is important, as some of the sugars have been depleted, rendering them ready to use (After prep, of course!). They're carefully selected by hand, rinsed, and inspected for consistent quality and value. These unique leaves have the added advantage of being quite attractive, larger in size than many of the other leaves commonly utilized in aquarium. Highly variable, almost no two being even close to alike-a super cool feature, in our opinion. They provide a terrific aesthetic for the natural aquarium! 

Magnolia leaves have a distinctive "look." Let's just say that, when you remove them from the context of the tree, they're downright "exotic-looking"- perfect for our uses!  They will darken over time after submersion, adding to their uniqueness. They are rather heavy leaves, which is great news, because it means they'll last a lot longer in a submerged state, so you don't need to replace them as often as you would, say, Catappa or even Guava.

Magnolia grandiflora produces phenolic antimicrobial chemicals, compounds called coumarins and sesquiterpene lactones, which discourage predation and grazing by terrestrial insects. Coumarins have known anti fungal properties. We can't help but wonder if these same antimicrobials and antifungals might-might provide some sort of benefits to fishes in a similar fashion to those attributed to Catappa, but this is just conjecture on our part; we am not aware of any specific scientific study on the matter, nor of the existence of data to confirm this theory. Let's just say that they do not seem to present any harm to our beloved aquatic pets.

We recommend that you rinse them well, then steep them in boiling (ore really hot) water for 10 minutes or so prior to use, and/or soak overnight in fresh water, which will help soften them a bit, and make them more palatable to shrimp, as well as to foster a "biofilm" on their surfaces, which provides supplemental grazing for shrimp and small fishes, and fry. And of course, it helps them sink more easily!

As far as tannins in the leaves, these leaves seem to contain quite a good quantity of them, and you will get a good, golden-brown tint with several leaves in a relatively modest-sized aquarium! Of course, the extent to which they will tint the water depends upon many factors, like how large an aquarium you have, how many leaves you tossed in, and if you are using any chemical filtration media, like activated carbon, etc., which will remove tannins almost as fast as they're released! 

Each package of our premium Magnolia leaves will come with several sizes, so that you can get some different aesthetic looks out of each one. These leaves can be used as a standalone shrimp feed, or incorporated as part of your aquarium's aquascaping as a component of leaf litter.

NOTE: Occasionally, these leaves may arrive with some mold or fungus on their surfaces. This is typically because their waxy "cuticle" does a really good job of retaining moisture, and in the confines of the plastic bag, a sort of "greenhouse effect" ensues. We've found that you can continue to use the leaves without any issues if you give them a little wipe down with a damp paper towel before preparing for use as instructed. If it's really bad, contact us and we will replace/credit as necessary!

Always go slow when introducing any botanicals into your systems, so you can judge the effect they have on your fishes and plants. They are not intended for human consumption. DO NOT INGEST!



NOTE: Since this is a natural product, each leaf will have a unique appearance. The photo is to provide you with an idea of what the leaves will look like and is not a representation of the exact leaves you will be receiving. leaves will often be broken on arrival.
