Skim Debris and Clean out Baskets
Skimming the pool’s surface by hand every few days is one of the fastest and easiest ways to keep your pool clean. Floating debris will eventually sink, making it harder to remove. Use a long-handled net called a hand skimmer or leaf skimmer to remove leaves, bugs and other unwanted items.
Skimming significantly increases the efficiency of the pool’s circulation system and lowers the amount of chlorine you’ll need to add to your pool. Cleaning out strainer baskets at least once a week also helps circulation and lowers chlorine demands. Locate strainer baskets attached to the side of aboveground pools and in the pool deck of in ground pools. Simply remove the plastic basket and shake it out; spraying the inside with a hose can help dislodge stubborn objects.
Vacuum the Pool and Brush Walls and Tile
A pool should be vacuumed every week to keep water clear and reduce the amount of chemicals you need to add to it. There are a few different kinds of pool vacuums, although the most common is known as a ‘Kreepy Krauly’ – an automated pool vacuum. If you happen to own a manual one, work it back and forth across the surface of the pool as if it’s carpet. It’s good form to slightly overlap each stroke. Check the filter each time you vacuum, and clean it if necessary.
But vacuuming isn’t the only weekly maintenance your pool requires. Brushing the walls and tile helps minimize algae build up and calcium deposits so they don’t fester and become larger problems. The material your pool walls are made of dictates what kind of cleaning tools you should use:
- For plaster-lined concrete pools, choose a stiff brush
- Vinyl and fibreglass walls can be cleaned with a softer brush
- Use a soft brush to prevent scratching tiles and degradation of grout – you can also use a pumice stone, putty knife of a half-half mixture of water and muriatic acid
Clean the Pool Filter
There are three kinds of pool filters: cartridge, sand and diatomaceous earth. While there are different maintenance procedures for each type, all require periodic cleaning depending on the type of filter and how often a pool is used.
It’s important to follow the manufacturer’s instructions here, as cleaning the filter more often than recommended can actually hinder the filtration process. This is because a clean filter isn’t as efficient as one with a mild amount of dirt in it to help trap other particles, which removes debris from the water. Just don’t let the filter get too dirty!
Keen at eye on the pressure gauge and flow meter to know when it’s time to clean your filter. The ideal time is when the difference reaches 10 to 15 pounds (4.5 to 6.8 kilograms) per square inch.
Professionally Service the Heater
Pool heaters typically require the least maintenance of all pool equipment. Gas heaters work fine without being serviced for a couple years, and electric ones can last even longer. You can consult the manufacturer’s manual for specific care instructions, however we highly recommend bringing in a professional, who will be able to disassemble the heater safely and quickly. The most common issue is calcium build up inside the tubes of a heater, which can restrict flow, preventing the water from heating adequately.
Check and Maintain Water Level
Most water loss occurs in the summer, largely because of evaporation and normal wear and tear, such as swimming, splashing and exiting the pool. So, when you remove debris with your skimmer throughout the week, take a moment check the water level. It’s important to ensure it doesn’t fall below the level of the skimmer, otherwise the pump could be damaged. If the water is low, use a garden hose to bring it up to safe levels.
If you drain your pool to perform maintenance or once the swimming season has passed, be careful to not let the pool sit empty too long. As a general rule, it’s best to leave water in a pool throughout the winter because the weight of the water counteracts with forces from the ground pressing up against the pool from below.
Maintain the pH Level
Pool water should be tested regularly to make sure it’s clean and healthy. The pH scale is a measurement of acidity or alkalinity that runs from 0 to 14. A reading between 7.2 and 7.8 is ideal; this range is safe for swimmers and helps sanitisers work at top efficiency.
You can monitor your pool’s pH level with a testing kit. There are many kinds of testing kits available; however, most homeowner versions are either reagent kits or test-strips. Reagent kits aren’t difficult to use. You take a sample of pool water, then add liquids or tablets to it. The water changes colour, indicating its chemical balance.
Test-strips work differently. When you submerge them in the pool for a few seconds, certain dyes they contain cause them to change colour. Next, match up the strip to a colour chart to determine the pool’s pH level. Use this information to gauge what kind and how much of the chemicals your pool needs.
Organic contaminants like ammonia or nitrogen build up in a pool over time. Massive amounts of such contaminants can interact with a pool’s chlorine to form chloramines, which give off that potent chlorine smell that many people associate with pools. To get rid of this harsh odour, it’s necessary to superchlorinate — or shock — pool water back to normal chlorine levels.
While it may seem counterintuitive, adding a large amount of chlorine to a pool can make the undesired odour go away. Some pools should be shocked once a week, while others can go a significantly longer time. Follow manufacturers’ instructions before superchlorinating your pool to get the best results.
Find and Repair Leaks
Sometimes it’s difficult to determine if low water levels are due to evaporation or a leak. You can uncover leaks in your pool by conducting a simple bucket test:
- Fill a plastic bucket three-quarters full of water
- On the inside of the bucket, mark the water line
- Place the bucket in the pool, and then mark the water line on the outside of the container (If the bucket has a handle, remove it to allow for better stability while floating)
- Let it float for two or three days
If the water inside and outside the bucket has gone down the same amount, your pool is losing water due to evaporation – simply refill with water from your garden hose. However, if the pool water level has gone down more than the water inside the bucket, your pool has a leak. That’s your cue to call a professional to have it patched.
Winterize Your Pool
Where you live determines whether or not you should winterize your pool. If your location experiences temperatures that drop below freezing, you’ll need to take steps to ensure that your pool stays healthy.
Residual pool water left in pipes can freeze and cause damage. To prevent this from happening, use an air compressor to blow water out of the pool’s plumbing when swimming season is over. Also, drain as much water as possible from the filter and heater. Any remaining water can be eliminated using nontoxic antifreeze (caution: this is different from antifreeze for vehicles). Disconnect the heater, pump and chemical feeders, the latter of which should be cleaned and stored.
Finally, clean the pool: skim, brush walls, vacuum, empty skimmer baskets, close skimmer line valve, lower water level to approximately 18 inches (45 centimetres) below the coping and supercholorinate. Lastly, cover the pool to keep out debris.
Open Your Pool for Swimming Season
If a pool is properly winterized, it can easily be reopened come swimming season. Firstly, don’t remove the pool cover until you’ve cleaned the area around the pool. Sweep or hose away debris to prevent it from getting into the pool, then use a garden hose to fill the pool to its normal water level. Reconnect everything that was disconnected. Water will need to flow through the circulation system, so open the skimmer line valve. Test the water for its pH level, then shock the pool. It’ll take a week or more before the pool gets balanced and becomes swimmable. Leave the pump running 24 hours a day, and reduce the run by only an hour or two each day until the water is balanced.
