AQUACULTURE TANKS
Built for Hatchery-to-Harvest Performance
Premium FRP Tanks Backed by Craftsmanship since 1991
Driven by curiosity and built on purpose, this is where bold thinking meets thoughtful execution in fiberglass aquaculture tank fabrication. Let's create something meaningful together.
Engineered Fiberglass Aquaculture Tanks Built for Production-Grade RAS Environments
LEVEL 08 manufactures commercial-grade FRP aquaculture tanks for recirculating aquaculture systems (RAS) and flow-through hatcheries, built to handle the load, chemical exposure, and sanitation demands of those environments.
Every tank has a smooth, non-porous gel-coat interior that minimizes biofilm adhesion and can be pressure-washed quickly between production cycles.
We stock a broad selection of round tanks for aquaculture, rectangular tanks, oval, and cone-bottom mold geometries for fast lead times, and we fabricate fully custom aquaculture fish tank solutions to your exact dimensions, drain configurations, and plumbing requirements. From a single replacement tank to a complete RAS build-out, our in-house design assistance ensures the right specification from the start.

ROUND TANKS
Level 08 Composite manufactures commercial-grade, UV-resistant round fiberglass aquaculture tanks, custom built for fish farms, RAS, and water storage maximize floor space, improve circulation, reduce stagnant zones, and simplify cleaning; oval and semi-square options available.
OVAL TANKS
Level 08 Composite manufactures custom oval fiberglass tanks built to your footprint and volume choose budget-friendly standard sizes or one-off custom builds. Add drains, windows, and bulkheads. Starting around 15 ft, ideal for large aquaculture and storage.
CONE BOTTOM TANKS
Level 08 Composite manufactures round cone-bottom fiberglass tanks for aquaculture and RAS, maximize gravity settling, concentrate biosolids fast, and purge sludge through a bottom discharge. Cleaner water, less maintenance, and customizable cone angles for reliable solids removal.
CYLLINDRICAL TANKS
Level 08 Composite manufactures custom fiberglass (FRP) tanks for aquaculture, water treatment, chemical storage & industrial applications using premium FDA-compliant isophthalic resin, CAD engineering, and corrosion-resistant fiberglass for exceptional durability.

Why Choose Fiberglass Aquaculture Tanks Over HDPE?
Fiberglass (FRP) tanks deliver long-term performance and easier upkeep for aquaculture operations and RAS tank integration—especially when sanitation, durability, and build quality matter…
-
Our tanks are finished with a smooth gel-coat surface that supports efficient cleaning and helps reduce buildup ideal for hatchery and multi-batch operations.
-
The glossy interior can be cleaned effectively with water pressure (and fish-friendly soap when needed), reducing downtime between cycles.
-
We manufacture with premium materials and controlled build standards to produce reliable tanks designed for demanding environments.
-
Choose from our standard tank offerings or request fully custom tanks built to your exact size, layout, and operational requirements.
-
We help you plan and select the right tank solution for your application so your setup performs the way it should from day one.
Built for Your Operation.

FREQUENTLY ASKED QUESTIONS
-
LEVEL 08 fiberglass aquaculture tanks range from 100-gallon units to 10,000+ gallons in round, oval, rectangular, and cone-bottom shapes. We also build custom aquaculture fish tanks to your exact footprint, drain layout, and plumbing requirements.
-
Round tanks are for RAS and hatchery setups, because circular flow improves water circulation and reduces stagnant zones. Rectangular tanks are used when floor space is tight or you need uniform racking, because it makes the best use of the layout.
-
For most commercial RAS and hatchery work, fiberglass is the stronger choice. The smooth, non-porous gel-coat interior resists biofilm buildup and can be pressure-washed quickly between production cycles, and we can build it with custom drains, cones, and bulkheads. HDPE can cost less upfront for small standard sizes.
-
Yes. Beyond our standard round, oval, rectangular, and cone-bottom molds, our team offers in-house design support to build a tank to your specific dimensions, capacity, and operational needs from a single replacement tank to a full RAS build-out.
-
Yes, our team works with customers throughout the design process to make sure the tank spec matches your application before fabrication starts.
