Complete multi-nutrient fertilizer for planted shrimp or freshwater fish aquaria with iron

Overview

  • Copper free and shrimp safe.
  • Provides 13 elements critical to long-term health, growth, and coloration of aquatic plants.
  • Elemental ratio reflects current understanding of general requirements for unrestricted growth of tropical aquatic plants.
  • May be used to establish beneficial water parameters in new aquaria, to replenish depleted elemental concentrations in aquaria that rarely receive a water change, and to re-establish concentrations in aquaria following large water changes.
  • Well-suited to the planted aquarium hobbyist seeking one simple solution to use for the majority of plant husbandry requirements (e.g. aside from instances when specific water parameters require adjustment).
  • Formulated utilizing extensive research on aquatic plant nutrient requirements and Shrimp Biotopes.

Technical Background

Nutrients are substances required by plants for survival; they are collectively involved in all aspects of the biological and chemical reactions that allow plants to function properly. Brightwell Aquatics Shrimp FlorinMulti provides these substances in concentrations found by researchers to be necessary for long-term health of tropical aquatic plants. These elements, and some of the processes that they are involved in, are:

Potassium - Protein synthesis, water and charge balance, enzyme activation.
Boron - Chlorophyll production, flowering, root growth, cell function.
Carbon - Required for all organic compounds.
Calcium - Cell wall stability and permeability, enzyme activation, cell response to stimuli.
Chlorine - Water and charge balance, photosynthesis.
Iron - Required for photosynthesis, component of enzymes utilized in redox reactions.
Magnesium - Component of chlorophyll, enzyme activation.
Manganese - Formation of amino acids, enzyme activation.
Molybdenum and Cobalt - Required for nitrate reduction.
Nickel - Enzyme activation, processing of nitrogenous material.
Sulfur - Component of proteins and the coenzymes that are involved with nutrient utilization and growth.
Zinc - Chlorophyll production, enzyme activation.

Note that Oxygen and Hydrogen are also required, but are available at all times through water, and so are not included in the list of components that comprise this solution. Shrimp FlorinMulti does not contain phosphorus or nitrogen; our extensive experience with planted aquarium husbandry has led us to believe that these nutrients should be added directly if/when desired by the hobbyist in accordance with plant needs, rather than in a broad spectrum nutrient solution.

Instructions & Guidelines

Shrimp FlorinMulti will help establish water chemistry conducive to long-term plant health and growth; specific nutrient requirements may be addressed with other Brightwell Aquatics supplements. Shake product well before using. Basic: For the first 3 - 5 weeks of use, add 2 ml (1 pump if equipped with a pump, or 2 threads on cap) of product per 6 to 10 US-gallons of aquarium water twice each week; increase dosage thereafter depending upon perceived nutrient needs of plants. Densely-planted aquaria and/or those that enjoy rapid plant growth (such as aquaria with intense lighting and CO2 supplementation) may benefit from more frequent supplementation. When used in this fashion, 500 ml treats up to 2,500 US-gallons (9,500 L). To increase plant growth rate, use Shrimp FlorinGrō+ together with this product.

Advanced: Daily dosing is recommended, as it maintains a more stable and natural environment than dosing weekly, in which nutrient concentrations spike just after dosing and then gradually decrease throughout the course of the week. To dose daily, add 6 drops per 20 US-gallons per day; adjust dosing volume after 3 - 5 weeks in accordance with appearance of plants and perceived need for nutrients. If, through continued dosing, the concentration of elements in an aquarium is in excess of that required by plants for continued health, some amount of enrichment may occur; this does not negatively impact the plants. Enrichment is minimized by ensuring that none of the nutrients becomes limiting to plant production, and in many cases the limiting nutrient will be carbon; in such instances, adding a carbon source can dramatically increase the rate of plant growth, and the growth rate itself may be controlled to some extent by regulating the amount of carbon made available. In this manner, the rate of plant growth may be made more manageable by the hobbyist if such rapid growth is unwanted.

Caution: Keep out of reach of children. Not for human consumption.

The best chew ever for a strong chewer
Color: Dogwood (Brown), Size: Large (Pack of 1)
We have a 77lb goldendoodle who loves these. We’re lucky because he doesn’t chew on anything other than his toys, but when he starts on this…he really goes at it. It’s healthy, (not synthetic), doesn’t break apart, (no pieces to worry about him swallowing), it just perfect for him. The noise may get on your nerves but it’s a small price to pay to keep him from chewing on your furniture, shoes, or anything else a mischievous dog can find.

Little pieces break off
Color: Dogwood (Brown), Size: Large (Pack of 1)
My dog is obsessed with this. It does last a long time even given her strong chewing capabilities. I wish it was a little bigger. The main reason I rated it so low is when my dog is chewing on this it breaks off a little plastic peice and sometimes it hits the back of her throat making her cough so you have to supervise with this.

Great for aggressive chewers
Color: Dogwood (Brown), Size: Large (Pack of 1)
My dog is an aggressive chewer so they are great for her. I would love to have one a bit thinner so it could fit in a holder so it is easier for her to hold while eating. This keeps her busy and is long lasting. I have purchased these multiple times.

Put your aggressive Chewer dog to the test!
Color: A Red, Size: For Larege Dogs
A very tough toy to stand up to my aggressive chewer lab! It's a great value! The squeak is not annoying, and she's got to clamp down hard on it. It's a nice throw toy! It bounces once or twice but it still brings out the pup in our Dog! Not too small a nice size for a Lab or retriever

A Hardy Toy for Chewers
Color: Bule Octopus, Size: For Larege Dogs, Color: Bule Octopus, Size: For Larege Dogs
I must say I was very surprised with the durability of this toy. We've had it for 3 days and not one puncture hole. My rescue is a destroy chewer that doesn't care for Hardy chew toys unless it squeaks. While the squeaker isn't the best, he still loves it. We put peanut butter in the grooves for him and he goes to town. Will purchase again should he ever destroys it, worth the price!
