Why 18 Ft Swimming Pool Covers Are Necessary
From my experience, having an 18 ft swimming pool cover is absolutely essential for anyone with a pool of that size. First, it keeps debris like leaves, dirt, and bugs out of the water, which saves me a lot of time and effort on cleaning. Without a cover, I found myself constantly skimming the surface and dealing with clogged filters.
Another reason I value my pool cover is safety. It provides a barrier that helps prevent accidental falls, especially if there are kids or pets around. Knowing my pool is covered gives me peace of mind, especially when I’m not home.
Finally, the cover helps maintain water temperature and reduces evaporation. I noticed that with the cover on, I didn’t have to refill the pool as often or spend as much on heating. Overall, investing in an 18 ft swimming pool cover has made pool ownership much easier and more enjoyable for me.
My Buying Guides on 18 Ft Swimming Pool Covers
When I decided to get an 18 ft swimming pool cover, I quickly realized there’s more to consider than just size. To help you out, I’m sharing what I learned through my experience—so you can make a smart choice without the hassle.
1. Know Your Pool Type and Size
First, I measured my pool carefully. Since I have an 18 ft diameter round pool, I needed a cover that would fit perfectly without being too tight or too loose. If your pool is rectangular or oval, make sure to get the exact dimensions to find a compatible cover. A good fit ensures better protection and durability.
2. Choose the Right Material
There are a few common materials for pool covers: polyethylene, vinyl, and mesh. I chose a heavy-duty polyethylene cover because it was affordable and great at blocking debris and UV rays. Vinyl covers tend to be more durable but pricier, while mesh covers allow water to drain but let small debris through. Think about your climate and what you want to protect against.
3. Consider the Cover Type
I found there are mainly two types: solid covers and mesh covers. Solid covers are excellent for keeping out leaves, dirt, and sunlight, which helps prevent algae growth. Mesh covers, on the other hand, let rainwater pass through but keep larger debris out. If you live in a rainy area, a mesh cover might save you from having to pump out water.
4. Look for UV and Weather Resistance
Since my pool is outdoors and exposed to the sun, I made sure my cover had UV protection. This feature extends the cover’s lifespan by preventing it from becoming brittle and cracking. Some covers also resist mold and mildew, which is a big plus in humid climates.
5. Check for Easy Installation and Removal
I wanted a cover that I could easily put on and take off without too much struggle. Some covers come with straps, clips, or even automated reels. If you’re like me and prefer convenience, look for covers with user-friendly features that save time and effort.
6. Safety Features Matter
If you have kids or pets, safety is a top priority. I chose a cover that is strong enough to support weight to prevent accidents. Some covers are certified safety covers, which can support the weight of a child or pet, giving peace of mind.
7. Budget vs. Quality
I balanced price and quality by reading reviews and comparing warranties. A cheaper cover might save money upfront but could wear out quickly. I recommend investing a bit more for durability and a good warranty—it pays off in the long run.
8. Maintenance and Storage
After using my cover, I learned that proper maintenance extends its life. Clean it regularly and store it dry during off-seasons. Some covers fold easily and come with storage bags, which makes the process much smoother.
Final Thoughts
Buying an 18 ft swimming pool cover was a straightforward process once I knew what to look for. By considering size, material, type, UV resistance, safety, and convenience, you’ll find a cover that keeps your pool clean and safe year-round. I hope my guide helps you enjoy your pool worry-free!
