Hey fellow aquarium lovers! Today I’m gonna share everything you need to know about using API Leaf Zone in your shrimp tanks. As someone who’s kept shrimp for years, I know how nerve-wracking it can be to add any new products to your carefully balanced ecosystem.
Quick Answer
Yes, API Leaf Zone is generally safe for shrimp when used properly. It contains minimal trace copper (around 0.002 ppm) which is well below harmful levels. However proper dosing and monitoring are essential.
What Exactly is API Leaf Zone?
API Leaf Zone is a liquid plant fertilizer that contains
- Potassium (for strong plant stems)
- Chelated iron (for photosynthesis)
- Manganese (helps nutrient absorption)
- Magnesium (boosts chlorophyll)
- Other trace minerals
Safety Considerations for Shrimp
The Copper Question
Let’s address the elephant in the room – copper content. Many shrimp keepers worry about copper because it can be toxic to invertebrates. Here’s what we know:
- API Leaf Zone contains no added copper
- Trace amounts (0.002 ppm) may exist from manufacturing processes
- Safe level for shrimp is under 0.3 ppm
- These trace amounts are lower than what’s found in green beans!
Potential Risks to Watch For
- Overdosing
- Can cause mineral buildup
- May affect water chemistry
- Could stress shrimp
- Water Quality Issues
- Surface film formation possible
- Might reduce oxygen exchange
- Can influence pH levels

My Personal Experience
I’ve been using API Leaf Zone in my cherry shrimp tank for about 8 months now Here’s what I’ve noticed
- Plants are growing much better
- No shrimp deaths related to the fertilizer
- Molt rate hasn’t changed
- Baby shrimp still appearing regularly

Common Questions I Get Asked
Q: Can I use it with crystal red shrimp?
A: Yes, but start with 1/4 dose as they’re more sensitive.
Q: How often should I dose?
A: Weekly is fine, but some prefer bi-weekly with half doses.
Q: What if I accidentally overdose?
A: Do an immediate 50% water change and skip next dose.
Bottom Line
API Leaf Zone can be a great tool for planted shrimp tanks when used correctly. Just remember:
- Follow dosing instructions
- Monitor your shrimp
- Maintain good water quality
- Start slow and adjust as needed

Fertilizers, Copper and Shrimp
Next up is the controversial trace element- Copper and its effects. Copper (Cu) has a positive and significant impact on plants. It is a naturally occurring element in the soil and has a lot of benefits to plants which includes the following:
- Promotion of healthy and sustainable growth
- Helps in the development and maintenance of plant parts
- Aids respiration and plant photosynthesis
- Aids enzymatic processes
The contrasting side of this element has to be that it is detrimental to the health of invertebrates- shrimp, snails, crayfish, and crabs inhabiting in the planted tank. This is usually common when exposed to high concentration levels.
The presence of copper in higher amounts disrupts their respiration, inhibits reproduction processes, and harms the immune system. Copper also affects the metabolism of aquatic species, higher concentration affects osmoregulation, molting frequently, and ultimately its survival.
Important: When purchasing fertilizers for planted tanks, it is strongly advised that you only obtain the ones that contain the lowest concentration of the copper element or does not have it at all. A lot of manufacturers will term their products will tag their products as ‘shrimp safe’ but you must study the composition of these products and pick out the most suitable one for your aquarium.
Trust me, you wouldn’t like to witness a scene whereby you dose plants with fertilizers and the shrimps start exhibiting adverse signs, and in some cases sudden death. Bear in mind that although copper is harmful to shrimp, it doesn’t mean you should never use plant fertilizers at all because they contain it. Avoid this misconception, all you have to do is watch out for the concentration levels, pick those with little traces or no trace at all and act accordingly.
To that effect, we will highlight safe shrimp plant fertilizers you can use in your planted tanks.
But first, why do plants need fertilizers?
Just like humans and animals need food for optimal growth, development, and survival, our aquarium plants also need this too but in the form of fertilizers.
The importance of fertilizers to the plants cannot be overemphasized, they need nutrients obtained from fertilizers for growth, development, vibrant coloration and other activities.
Plants need quite a wide range of crucial elements for healthy growth. Some of these elements are required in large amounts (macro elements) while some are needed in very little amounts (trace elements).
Macroelements include the popular trio- Nitrogen, Phosphates, and Potassium (NPK), other notable ones like Calcium, Magnesium, and Sulphur. Trace elements involve the totality of elements like Zinc, Iron, Copper, Chloride, Manganese, Boron amongst others.
