Turn this result into 1–3 supplier quotes

Send this spec privately to selected manufacturers.

FishMatch Group reaches out on your behalf — your name, project and location stay confidential until you accept a quote. No sign-up, no listing fees, buyers never pay.

How supplier matching works

  1. 1. Private brief. Your spec goes only to manufacturers we have selected for the right category, capacity and export experience.
  2. 2. Confidential outreach. Suppliers see the technical spec — not your name, company or exact location — until you accept a quote.
  3. 3. 1–3 comparable quotes. Typically within 5–10 business days, aligned on scope so you can compare like-for-like.
  4. 4. Financing intro (optional). If needed, we introduce your project to a financing partner. No fee to buyers.

Notes

  • RAS best practice: 30–90 min turnover for finfish, 15–45 min for high-density systems.
  • For dual-drain tanks, reduce working depth by 5–10% to account for the center-sump cone.
