Buying Guide
What should I look for in a 35 gallon poly tank?
Consider material quality, lid design, opening size, and portability. Look for UV resistance for outdoor use and a lid or locking lid if security is important. A clear sight line for liquid levels helps with monitoring. If you plan to pump or drain through tubing, ensure there is a compatible opening or vent.
Which tank is best for indoor vs outdoor use?
Locking lids and robust seals are better for outdoor or shared spaces. Tanks with UV resistance are preferred outdoors. Indoor setups may prioritize compact dimensions and easy access to the top opening for maintenance.
Do I need a square or horizontal orientation?
Vertical tanks save floor space in compact areas; horizontal or low-profile tanks fit under eaves or along walls and are easier to transport on trailers. Your space and transport method will guide orientation choice.
What about transport and mounting?
Tanks with tie-down channels or carrying handles simplify secure transport. For portable use, a lighter 26–30 gallon model can be easier to move. Always secure tanks during vehicle transport to prevent movement and damage.
Are there any cautions to consider?
Verify chemical compatibility with your contents, especially if storing corrosive materials. Check openings, lids, and seals for wear to prevent leaks. For outdoor storage, ensure the tank is rated for UV exposure and weather resistance.
