Simple Tips for Clean, Clear Water

Keeping water clean in a stock tank pool takes a bit of care Here’s how to keep the water fresh, clear, and algae-free:

Using a Filtration system

Our Poolex Filter Pro keeps water circulating and filtered, preventing stagnation and debris buildup.

Run it at least 4–6 hours per day depending on use. We run our filter 24/7 for our 6ft round stock tank.

Make sure to rinse the filter cartridge weekly.


 If unfiltered Change the Water

Without a filter, plan to drain and refill every 1–2 weeks in hot weather.

Never use Chlorine without the Filter pump. This will cause Chemical damage to your tank.


Regular Cleaning

Skim debris daily (leaves, bugs, etc.).

Scrub the sides and bottom weekly — algae clings easily to metal.

Clean the filter every week.


Cover When Not in Use

A pool cover or shade sail helps:

Prevent debris.

Slow algae growth.


Chemicals have a negative impact on the lifespan of your Tankkd.

Therefore, we use as little as possible.

Use only:

• 1 tablet every 1 to 2 weeks

• Maximum 5 grams

• Always in a floating dispenser, never directly in the tank

❌ Never use Chlorine without filter



pH Management

Testing

Use pool test strips to measure pH.

Test every few days, especially after heavy rain, refilling, or lots of swimming.

If pH is Too Low (<7.2)

Add pH increaser (sodium carbonate / soda ash).

Start with about 1 tablespoon per 100 gallons, mix, then retest in a few hours.

If pH is Too High (>7.8)

Add pH reducer (sodium bisulfate or muriatic acid).

Start small: 1 teaspoon per 100 gallons, stir well, and retest.
