Above-ground pool maintenance: the right way to do it
There is no need to overcomplicate things. The ideal routine is straightforward: get rid of debris, ensure the water is moving, give the filter a once-over and test the water with some regularity. In the end, being consistent is far more valuable than an occasional deep clean. For the above-ground pool owner, the key is to stay on top of maintenance so you are not left dealing with cloudy water or algae.
Daily chores and after heavy use
Tend to the obvious first:
- Skim off any leaves, insects or other floating matter before it has a chance to sink.
- Make sure the skimmer can do its job by checking the water level.
- Give the pump and filtration system a look to see they are in good working order.
- Be on the lookout for any odd cloudiness, foam or a sharp chemical odour.
Debris left to sit will clog the skimmer basket or put a stain on the liner. A pool cover is a good way to keep things tidy between swims, but be sure to handle it as the manufacturer intends.
Your weekly regimen
Stick to a pattern each week to nip small issues in the bud:
1. Brush up. Go over the walls, floor, steps and accessories to dislodge dirt and the beginnings of algae; this is worthwhile even if the water appears clear. 2. Vacuum. This will take care of whatever the brush loosened. 3. Empty the skimmer basket. Turn the pump off before you open it. 4. Check the pump and filter for any leaks or trapped material. 5. Put the water to the test and make any necessary adjustments per the manual and chemical labels.
A spike on the pressure gauge, if your pool is so equipped, is usually a sign the filter is due for a cleaning.
Water chemistry done safely
For a pool that is both safe and clear, the chemistry has to be in balance. Put in the time with a test kit to monitor pH, alkalinity and sanitizer levels as your manual advises.
- Stay within the range specified for your equipment when it comes to chlorine or other sanitizers.
- Never mix products unless the instructions tell you to, and always wear the proper PPE. Do not make guesses on how much to add.
- Should the water turn green or remain hazy, do not assume it is a lack of chlorine; there may be something amiss with the circulation, filtration or your testing.
Under no circumstances should one swim in water that is visibly unsafe or where you suspect an electrical problem.
Caring for the pump and filter
These are the heart of the operation, doing the work of sanitation and debris removal. Follow the owner’s manual for the number of hours to run the pump daily and for cleaning the filter. If you have a sand filter or similar setup that calls for backwashing, do it by the book. It is better to consult the exact manual for your model than to force a step on a system you are not familiar with.
Pitfalls to steer clear of
Most trouble stems from shortcuts or neglecting the fundamentals. Avoid running the pump with low water, leaving the skimmer basket to overflow, or trying to clean equipment while the pump is still on. Do not reach into operating suction outlets or attempt to fix electrical faults yourself. And always read the label before handling chemicals.
Time to bring in an expert?
You should put in a call to a qualified professional or electrician if you encounter any of the following:
- Cloudy water that will not clear up with normal attention
- A pump that is losing prime, making noise or leaking
- Unusual behaviour from the filter, pressure gauge or circulation
- Any sign of a tear in the liner or a frame issue
- Damaged wiring, tripped breakers or sparks
Let a pro handle the troubleshooting of structural or equipment matters while you continue with the day-to-day observation and cleaning.
