Fiberglass Pool Maintenance Made Simple

Taking care of a fiberglass pool is much easier than most people think. With a simple routine in place, you can keep the water clean, protect your gelcoat, and enjoy a sparkling pool all summer. Here is a clear guide you can follow each week to care for your fiberglass pool and help it last for many years.

Quick Answer: What Does Fiberglass Pool Maintenance Include?

Fiberglass pool maintenance includes weekly brushing, vacuuming, testing your water chemistry two or three times a week, keeping water levels above the skimmer, and inspecting your filter and equipment each month.

These basic steps help protect the gelcoat, prevent algae, and keep your water clear.

Assess the Condition of Your Pool

Regular fiberglass pool care includes inspecting the pool and mechanical systems for damage, which is one of the most important steps to staying ahead of any issues. You’d be surprised at how quickly things can take a turn for the worse if you don’t regularly inspect for any visible signs of wear or damage.

Take a minute to also check pumps, filters, and other mechanical systems outside it. Catching any potential problems early means being able to address them promptly.

Clean with Products Made for Fiberglass

Keeping your pool clean and properly maintained is essential to ensure it remains in top condition. To prevent any damage to your fiberglass pool, be sure to use cleaning products made specifically for this type of material, such as skimmers or a pool vacuum. Not only can vacuuming and brushing regularly with a brush suitable for fiberglass help keep the surface clean, but it also allows you to get rid of debris on the floor of your pool so that it stays crystal clear. Plus, with some maintenance, your pool should remain in great shape for many years!

Maintain the Water Chemistry

Maintaining your pool’s water chemistry is essential when it comes to creating a safe and inviting environment for swimmers. pH levels are one of the most important measurements to pay attention to, with a range from 0 – 14 indicating acidic (below 7) or alkaline (above 7). It’s recommended to keep your pool’s pH levels between 7.4 and 7.6 because the level outside this range can cause irritation for both humans and equipment. To properly maintain the water chemistry in your pool, test pH levels regularly and make adjustments if needed using common substances like muriatic acid or sodium carbonate. With frequent testing and adjustment, you can ensure that you have a perfect balance in your pool every swimming season!

Simple Water Chemistry Tips:

  • Test your water two or three times a week
  • Use pH increaser or pH reducer when needed
  • Keep chlorine levels steady
  • Check alkalinity and calcium hardness

Regularly Check the Filter System

Regularly checking and cleaning your pool’s filter system will keep your water clear and your filtration system running at its best. Not only does this help reduce the inevitable build-up of algae, but it also ensures that your filter system works at optimum levels for maximum efficiency. You might find it helpful to add cleaning your filter system to your weekly maintenance list. Keep in mind – the better the filter system works, the fewer times you’ll have to dive into the deep pool clean.

Check Your Water Levels – Keep Water Levels Above the Skimmer

Keeping the water level in your pool above the skimmer is essential for keeping the water sparkling clean. Without power to draw in water from the pool, skimmers are reliant on free flow into their little baskets. Rising too low can mean debris will accumulate and clog up your filter pump, leaving you with tacky, cloudy patches throughout the pool. That’s why it’s important to diligently check your pool’s water level.

How to Clean a Fiberglass Pool Step by Step

This simple routine works for most families.

  1. Skim the surface
  2. Brush the walls and steps with a fiberglass-safe brush
  3. Vacuum the floor
  4. Check the water level
  5. Test pH and chlorine
  6. Empty the skimmer baskets
  7. Clean or backwash the filter
  8. Add shock if needed
  9. Do a quick equipment check

Following these steps once a week helps your pool stay fresh and clear.
