PolyTanks

PolyTank offers a variety of tanks and tank systems for both educational and aquaculture applications. Great tanks for koi display and holding. Tanks also work well for fish culture, filtration, temporary holding tanks and much more! Tanks are lightweight, inexpensive, freshwater or saltwater compatible and have a long life expectancy. Their smooth surface makes them easy to clean.

All tanks are one piece and do not have factory installed drains, use bulkhead fittings for water tight drain connections. Tanks are shipped from Minnesota. Please allow 10 to 14 days for delivery time. All tanks are available in black, green, blue or natural. Tanks ship blue if not specified.
