Polypropylene Tank for Aquaculture, Storage, and RAS Systems

This tank isn’t trying to look fancy. It’s built to stay quiet and do its job — day in, day out — without cracking under UV, leaking at the seams, or rusting from salt exposure.

Material
It’s made from polypropylene (PP) — not the recycled mix, but stable, UV-resistant, and chemically non-reactive grade. That means it won’t degrade when exposed to strong light or corrosive water chemistry, which is exactly what you’re dealing with in RAS or open-air hatchery systems.

What it handles well
You’ve got oxygen-rich flows, brackish backwash, sometimes even chemical dosing — and most tanks don’t like that mix. Coated steel eventually flakes. PE tanks bow or get brittle in the sun. PP holds shape and doesn’t leach or absorb.

Where it fits
Operators use these tanks across the loop:

as sump basins catching debris before filtration

as holding tanks for broodstock or fingerlings

as buffer tanks feeding steady flow into skimmers or protein separators

as chemical mix tanks for pre-dosing ozone, chlorine, or probiotics
All of that shows up in actual layouts across YUTANK’s RAS equipment catalogs.

Access & cleaning
Designs are simplified for actual use: flat base for secure install, optional access hatch, fittings at user-specified positions. That means no more fighting gravity when draining, and no awkward reach-in scrubs during downtime.

Customization
Dimensions, fittings, and panel reinforcement are all open. You’re not locked into one layout — the production process supports variant sizes, so your team can spec it tight to your floorplan.

No marketing magic here. Just a tank that shows up, fits in, and doesn’t give you trouble three months later.
