Stock Tank Pool FAQ

Everything you need to know about setting up, maintaining, and enjoying a stock tank pool. Click any question to jump to the answer.

What size stock tank pool should I get?

The most popular size is the 8 ft galvanized tank, which holds about 700 gallons and comfortably fits 2–3 adults. The 6 ft tank works for individuals or couples and fits well in smaller spaces. The 10 ft tank is the largest practical option (~1,500 gallons) and works best for large families or entertaining.

Key sizing factors: How many people will use it, available yard space. Larger tanks are not always better! 

Do I need a pump for a stock tank pool?

Yes — a pump and filter are non-negotiable. Without circulation, water will turn green within a few days regardless of how much chlorine you add. A recirculating pump moves water through a filter that removes debris and maintains water clarity.

The STPP DIY Pump Kit ($409.99) includes everything: 1500 GPH pump with filter, two threaded assemblies, two plunger valves, sealant, and hole saw. It installs in about 45 minutes.

How do I keep a stock tank pool clean?

Three-part routine:

1. Daily: Run pump 2-6 hours, check chlorine dispenser has tablets
2. Weekly: Test water chemistry (target: chlorine 1–3 ppm, pH 7.2–7.6), rinse filter cartridge, vacuum the bottom
3. Monthly: Replace filter cartridge if flow drops, chemistry check, and add water to the pool as needed. Some will evaporate naturally.

The Blue-Water Vacuum V2 makes weekly pool cleaning a 10-minute job without draining.

Why is my stock tank pool turning green?

Green water = algae = chlorine has dropped too low. Troubleshoot in order:

• Is the pump running 2-6 hours daily?
• Is the filter cartridge clogged (reduced flow)?
• Does the chlorine dispenser have tablets?

Recovery: Vacuum the bottom, add a chlorine shock dose, run the pump continuously for 12 hours. Water should clear within 1–2 days. Then resume normal maintenance.

How much does a stock tank pool cost?

Complete first-season setup:

• 8 ft galvanized tank: ~$575
• STPP DELUXE Pump + Vacuum Kit: $499
• Chlorine, pH chemicals, test strips: ~$60
• Filter cartridges (season): ~$60
• Total: ~$1,200

Ongoing annual costs: $100–$150 in chemicals and filter cartridges.

How long does it take to set up?

Pump installation: ~45 minutes. Filling with a garden hose: 2–4 hours (depending on tank size and water pressure). 

Do galvanized tanks rust?

Galvanized steel is zinc-coated and rust-resistant. Tanks last many seasons with proper care. The key is maintaining pH at 7.2–7.6 — acidic water (low pH) accelerates corrosion and leaches zinc faster. Check pH weekly.

Where can I buy a stock tank?

Our preferred supplier is www.tankandbarrel.com. They can ship a wide range of tank sizes, poly or galvanized directly to your house. You can also source tanks locally at your nearby farm or tractor supply store. The most accessible pools will be 6 ft and 8 ft tanks. For 10 ft tanks can be found but often require a special order. Many farm supply stores will also deliver the tanks to your house. 

Can I heat a stock tank pool?

Yes, but it will require a 220 volt power outlet, or propane/natural gas. Stock Tank Pool Products is developing a heater to extend your pool season, check back regularly for updates.
