Powders dissolve.

Gels persist.

By holding iron within a biodegradable gel matrix, AGP Iron Gel is designed to slow loss of availability and reduce sensitivity to system chemistry changes.

The material itself is a key part of the strategy, not just the iron it contains.

Find our founder at the upcoming Indoor Ag Conference and Aquaculture America if you'd like to learn how the AGP Iron Gel gives your plants extended access to tricky nutrients!

Most synthetic iron chelators are only effective within a narrow pH range.

When system pH drifts outside that window, iron becomes unavailable, even if it is still present in the water.

This creates a cycle of re-dosing rather than long-term stability.

We’re developing AGP Iron Gel to remain stable across a much wider pH range commonly seen in recirculating systems.

Iron deficiency is one of the most common nutrient problems in aquaponics, hydroponics, and controlled environment agriculture (CEA).

In recirculating systems, iron becomes unavailable over time due to system chemistry, pH shifts, and interactions with other compounds. Even when iron is added, much of it does not stay accessible to plant roots.

Most farms rely on synthetic chelated iron to correct this problem. While effective in the short term, powdered chelates are sensitive to pH, prone to binding out, and often require repeated supplementation. This creates nutrient spikes, crashes, and constant adjustment.

At AGP Substrates, we take a different approach to iron management.

AGP Iron Gel is a next-generation CEA substrate designed to stabilize iron near the root zone instead of repeatedly forcing it into the water column. By holding iron in a biodegradable, plant-based gel, AGP supports more consistent iron availability across changing system conditions.

The result is fewer corrections, more stable plant nutrition, and iron management that works with recirculating systems instead of against them.

This is how iron management evolves in aquaponics and hydroponics.

At AGP, we are so grateful for the farmers who are rethinking how we grow food and protect our waters.

Thank you for believing in sustainable solutions and supporting AGP Substrates.

Happy Thanksgiving!

We are so excited to share results from a recent case study with Olive Branch Aquaponics 🌱

Pepper plants in an aquaponic media bed were supplemented with the AGP Iron Gel, a plant-based and biodegradable alternative to synthetic chelated iron.

📊 Before: plants exhibited interveinal chlorosis (yellowing leaves with green veins), a classic sign of iron deficiency.

🌿 After: 60 days later, plants developed uniform, dark green foliage, demonstrating restored iron availability and improved overall health.

By delivering micronutrients that remain plant-available in a gel form directly to the root zone, dosing becomes more efficient than with powders that often precipitate, have a narrow pH range, and require higher chemical inputs.

With AGP Iron Gel, we are able to use fewer chemicals while achieving stronger plant performance ✅

This study highlights the potential of biodegradable nutrient inputs to simplify management, replace synthetic supplements, and strengthen aquaponic systems.

Most importantly, this represents a step forward in our mission to advance sustainable food production systems that protect coastal ecosystems from nutrient pollution!!! 🌊

Day one at Aquashella was a huge success, and we are proud to introduce the HappiFilter to the aquarium community. 🌊🐟

What makes this filter unique is that it is inspired by aquaponics, the same sustainable growing method used by commercial farmers who raise fish and plants together in a closed-loop system. By reducing nitrate buildup and cutting down on water changes, the HappiFilter brings those principles into home aquariums in a way that is practical, effective, and sustainable.

When we understand the growing methods behind our food and the systems that support them, we can advocate for more sustainable choices in our daily lives. That creates demand for aquaponically grown plants and food in our local stores and restaurants.

The HappiFilter is more than just a filter. It is a bridge that connects home aquarists to the larger vision of sustainable farming and food production. And this is only the beginning. 💡🌱

We couldn’t be more proud to celebrate this milestone 🎉 Our HappiFilter aquaponic aquarium filter is officially patented! 🌱🐟

What started as a student pitch at the BGSU Hatch has grown into a mission to make aquariums more sustainable and connect more people to aquaponics as a solution for protecting coastal ecosystems. 🌊💚

This is just the beginning — thank you to everyone who has supported us along the way!

🎉 Big news from the HappiFilter team! 🎉

Our aquaponic aquarium filter is now officially patented! 🌱🐟✨

This journey started back in 2023 when our founder first pitched the idea at the BGSU Hatch program. Since then, HappiFilter has grown into a startup with one mission: to make aquariums more sustainable while connecting more people to aquaponics as a solution for protecting our oceans and coastal ecosystems. 🌊💚

We’re so grateful for the support, mentorship, and legal guidance that helped us reach this milestone. And we’re just getting started. 🚀

Here’s to healthier aquariums, stronger connections to sustainable food systems, and protecting the planet one tank at a time!
