Troubleshooting Common Pool Opening Issues

A good pool closing sets the scene for a faster, better pool opening, and although you can certainly minimize the potential for issues, you can’t always avoid them completely.

Know Where to Start

Begin by using a pressure washer to thoroughly clean the pool cover, accessories, deck, and other pool components. Take the cover off, fold and put in the cover bag. Next, reinstall all pool equipment, including jets, lights, ladder, and diving board.. Reassemble pool equipment and start the circulation. Vacuum the pool bottom carefully, preferably with dirty water going to waste. Shock the pool water with chlorine either liquid or granular to raise the free chlorine level to 10 ppm. Scrub the pool walls with a brush, and clear the surface of the water.

Symptoms of Issues

Next, examine your pool carefully and test the water. Pay close attention to these key symptoms and their corresponding underlying issues:

• Cloudiness: Cloudiness in the water could be a sign of algae growth, poor filtration, or improper chemical balance.
• Visible Algae Growth and Discoloured Water: Green, black, or yellow algae can grow on pool surfaces or in the water, indicating poor sanitation or insufficient chemical treatment.
• Foul Odor: A strong odour emanating from the water can indicate the presence of algae, bacteria, or other contaminants.
• Debris Accumulation: Leaves, twigs, and other debris may have accumulated in the pool, even if covered.
• pH Imbalance: Testing the pH level of the water may reveal imbalances which can lead to discomfort for swimmers and promote algae growth.
• White, Chalky Deposits: These signs of calcium deposits indicate high calcium hardness levels, which can cause scaling and other problems.
• Staining: Stains on pool surfaces, particularly near metal fittings or along the waterline, could indicate mineral imbalances or the presence of metals in the water.
• Liner Damage: Vinyl liners can be susceptible to tears, punctures, or stretching from freezing temperatures.
• Structural Integrity: Check the pool's structural integrity, including walls, steps, and coping stones, for any signs of movement or damage caused by freezing and thawing cycles.

Troubleshooting

Algae and Bacterial Buildup

Algae and bacteria can build up in the water remaining after draining, even in cool weather. While algae growth may be less prevalent during winter, it can still develop in stagnant water in the spring before or during opening. Shock treat the pool with a high dose of chlorine to eliminate any existing algae and prevent future blooms. Regularly brush and maintain the pool surface to inhibit algae growth and maintain water quality.

Water Clarity and Debris Removal

Debris accumulation can occur, even with winterization. Start by removing any debris with a skimmer or net. Thoroughly vacuum the pool to clear the bottom and walls. A pool brush can loosen stubborn debris before vacuuming. This process may need to be repeated a couple of times. A thorough backwashing of the filter and a clarifier or enzyme treatment will also help to restore water clarity.

Liner and Pool Damage

Repair minor liner damage promptly using a vinyl patch kit; however, it’s recommended to contact a professional to thoroughly assess any damages and conduct any repairs.

pH Imbalances

While a pH imbalance in pools can be caused by sweat or chemical treatments, in spring, it can often be caused by rainwater or debris seeping in. Make sure to clear all debris out completely before trying to correct the pH balance. Use a reliable testing kit, and, as indicated, add a pH increaser or reducer per the manufacturer's recommendations. Re-test and adjust if needed. A stabilizer or buffer may help. 

Calcium Deposits

These can happen from evaporation, dissolved minerals in the fill water, or chemical imbalances. Test the calcium hardness level of the pool water using a reliable test kit. A specialized calcium hardness reducer or flocculant can help. Diluting by partially draining and refilling may be necessary. 

Metal Ions

Copper stains appear as blue or greenish-blue patches and result from copper-based algaecides, copper pipes, or copper-containing pool equipment. Rusty iron stains are often caused by corroded metal fittings or oxidized iron in the water supply. Manganese stains are uncommon, appearing as dark brown or blackish spots. Manganese contamination can occur from well water or water treatment processes. Tests are available to confirm the presence of these metals and special products to treat the issue. Shocking pool water can help as well. It’s important to identify the underlying cause of the contamination.

When to Consult a Professional

Professionals often have access to more advanced water testing equipment for a more comprehensive analysis.

If you're struggling to balance chemicals or pH levels or have additional features like a spa, fountain, or automated chemical dosing system, seek help, rather than risk having unsafe water.
