Why Pool Covers 18 Ft Are Necessary
From my experience, having an 18 ft pool cover is absolutely essential for anyone with a pool of similar size. First, it helps keep the water clean by preventing leaves, dirt, and debris from falling in. This means I spend far less time scrubbing and more time enjoying my pool. It also helps reduce evaporation, which saves water and keeps the chemical balance more stable.
Another reason I find an 18 ft pool cover necessary is safety. It acts as a barrier to prevent accidental falls, especially if you have kids or pets around. Plus, covering my pool helps maintain warmth, extending the swimming season and lowering heating costs. Overall, an 18 ft pool cover is a simple investment that makes pool maintenance easier, safer, and more cost-effective.
My Buying Guides on Pool Covers 18 Ft
When I was searching for the perfect pool cover for my 18-foot pool, I realized there are a few important factors to consider to make the best choice. Here’s what I learned along the way that might help you too.
1. Know Your Pool Type and Shape
The first thing I did was confirm my pool’s exact size and shape. Even though my pool is 18 feet in diameter, it’s important to know if it’s round, oval, or custom-shaped because not all covers fit every shape perfectly. For round pools, many covers come in standard sizes like 18 ft, but if you have an oval or irregular shape, you might need a custom cover or one that offers some adjustability.
2. Decide on the Cover Material
There are several types of pool cover materials I came across:
- Solar Covers: These are lightweight and help heat the pool by trapping sunlight. I liked that they also reduce evaporation, but they don’t provide much debris protection.
- Winter Covers: These are heavier and designed to keep leaves, dirt, and snow out during the off-season. I went with a winter cover since my area gets a lot of autumn leaves.
- Mesh Covers: They allow water to pass through but keep debris out. I considered these, but I preferred a solid cover to keep everything out.
- Solid Covers: These block debris and sunlight completely, preventing algae growth. They tend to be heavier and require a pump to remove rainwater.
Choosing the right material depends on your climate and how you use your pool.
3. Safety Features Matter
If you have kids or pets, safety is a top priority. I looked for covers labeled as “safety covers” that are strong enough to hold weight and prevent accidental falls. These often come with reinforced straps and anchors. While they tend to be more expensive, I felt the investment was worth the peace of mind.
4. Installation and Ease of Use
I considered how easy the cover would be to install and remove. Some covers come with automatic reels or rollers, which make handling an 18 ft cover much simpler. If you don’t want to struggle every season, investing in a cover with user-friendly installation options is a good idea.
5. Durability and Warranty
Since pool covers are exposed to sun, water, and weather, durability is key. I checked for UV resistance and tear strength in the product descriptions. A good warranty was also a major plus—it showed the manufacturer’s confidence in their product.
6. Price vs. Value
I set a budget but also weighed value over just price. Sometimes spending a bit more upfront on a quality cover saves money on maintenance, repairs, or heating costs down the line.
7. Additional Accessories
Some covers come with anchors, straps, or pumps for removing water accumulation. I made sure my purchase included or allowed me to buy these extras easily, so I wouldn’t have to hunt for compatible parts later.
Final Thoughts
Buying an 18 ft pool cover is not just about size; it’s about matching the cover to your pool’s shape, your climate, safety needs, and how you plan to use it. After considering all these factors, I found a cover that keeps my pool clean, safe, and ready for swimming season. I hope my experience helps you find the perfect pool cover too!
