You can find the answers to many questions about mixing and dosing with water-soluble plant nutrients, and shipping, both domestically and internationally in the FAQ page.
Why shop with us?
Why buy water with a small amount of plant nutrients when you can buy nutrients and add your own water?
Nutrients for aquatic plants are not hard to find. You can go to any pet store or to the big pet suppliers online. The nutrients you buy from these suppliers come already mixed with water. You are paying for water and the cost of shipping water. We think you have plenty of water if you have an aquarium.
AquariumFertilizer.com carries water-soluble nutrients and water conditioners made from naturally occurring ground minerals. We carry the nutrients required by all plants: Macro Micro Nutrient Mix; Nutritrace CSM + boron; calcium compounds for water conditioning including Barr’s GH Booster; and 3 chelated iron compounds. We also carry 16-ounce Graduated Dispenser bottles for ease of mixing and dosing that can be purchased alone or in combination with select pre-blended nutrients at a discount.We offer a 10% discount to aquarium and aquatic plant society, association, club, blog and forum members in exchange for putting our link on the group website or social media page.
Shipping is by USPS flat rate priority mail. Up to 6 lbs can be shipped by flat rate envelope and up to 20 lbs ships in a medium flat rate box. Information about shipping costs and delivery time is available in our FAQ page. Information about international shipping is also available in the FAQ page. There is a strict limit of 4 lbs that can be shipped internationally in a flat rate envelope and a limit of 20 lbs in a medium flat rate box.
Dry nutrients in small quantities are harder to find. AquariumFertilizer.com was founded as a less expensive place to buy dry nutrients in manageable quantities. We sell you the nutrients and you add the water. By doing so you save many times what you would pay for premixed bottled nutrients. An added benefit is that you can design your own nutrient blends. Or buy our premixed Macro Micro Nutrient Mix or Macro Mix and still save a bundle! These products are suitable and practical for hydroponics, aeroponics and garden ponds.

About Us
Julia Adkins
I am a long-time gardener who enjoys plants of all kinds. I use my own products to support the health and growth of both my terrestrial and aquatic plants. My knowledge of plant nutrients and their uses comes through growing aquatic and terrestrial plants. This experience is backed by university-level chemistry and biology courses.
Amanda Adkins
I am the second generation to help manage this business. I was lucky to be taught the love of gardening by both my grandmothers and my mother. My paternal grandmother grew heirloom roses, succulents, and crafted bonsai. My paternal grandmother was a passionate rose gardener. From my mother I learned about aquatic plants. I have earned degrees in science, mathematics, engineering, and physics.
