Koi vs. Shubunkins with Water Hyacinths: Salt and Stocking

Koi vs. Shubunkins with Water Hyacinths: Salt and Stocking

New 1000-gal pond owner cleaned, added filtration, waterfalls, dozens of blooming water hyacinths, grasses, lilies. Cycled pond. Debated: 6-8 koi vs. 2 dozen shubunkins. Koi eat hyacinth roots? Follow-up: chose shubunkins, asked about pond salt with plants.

Koi and Hyacinths

• Koi nibble hyacinth roots. Small koi = minimal damage.
• Many hyacinths + few koi = sustainable.
• Koi experts: 1000 gal for first koi, 100 gal each additional. Your pond = 1 koi max.

Better Choice: Shubunkins

• Smaller, less destructive.
• Colorful, hardy.
• Will spawn — plan for population control.
• Understock initially (1 dozen) until biofilter matures.

Pond Salt with Plants

• Koi experts use 0.1% — kills plants, snails, sensitive fish.
• Safe level: 0.05% or less. Plants tolerate; still deters parasites/bacteria.
• Salt helps fish osmoregulation (less pumping effort).
• Use spring only (parasite peak) or therapeutic.

Summary

Shubunkins + hyacinths + 0.05% salt = balanced, beautiful pond. Don't overstock. Enjoy!
