Solid, heavy-duty cover that keeps debris and heat out of a 100-gallon tank.
Imagine you buy a 100-gallon stock tank for cold plunges, horses, or backyard watering. Leaves, rain, and sun beat it up fast. You want something that seals, drains, and zips on easily so your water stays cleaner, warmer, and ready when you are. This cover aims to do that—keeping water usable and equipment protected with minimal fuss.
Is MQLD Rubermaid 100 Gallon Waterproof Stock Tank Cover with Zipper Good?
Yes — for most outdoor tank owners, it’s a practical, robust choice. I found it especially useful when I needed a fast way to protect a 100-gallon trough from storms and falling debris. It’s best for people who want a durable, waterproof top that zips on and reduces evaporation. In my yard, the cover kept leaves and algae out for weeks longer than a loose tarp did. Another time, I used it over a cold plunge tub and noticed the water stayed a touch warmer overnight. If you want simplicity, durability, and a tighter seal than an ordinary tarp, this cover fits the bill.
My First Impression for MQLD Rubermaid 100 Gallon Waterproof Stock Tank Cover with Zipper
The cover arrived neatly folded in a compact bag. Packaging was clean and the material looked thick. When I first handled it, the fabric felt heavy and stitched seams looked solid. The zipper felt strong and the edges had reinforced hems. Setup was simple — place it over the tank and zip around the rim. It fit snugly and did not flap in wind. My initial reaction: pleasantly surprised. I expected a lighter tarp, but got a near-purpose-built cover. That made me hopeful it would last through seasons.
What Makes It Stand Out / Key Features
- Waterproof heavy-duty fabric that sheds rain and prevents pooling
- Full-length zipper for easy on/off access and secure closure
- Reinforced edges and seams for wind resistance
- Insulating layer to help reduce heat loss and evaporation
- Custom fit for 100-gallon rectangular/oval tanks—minimizes flapping
- Lightweight enough to store when not in use but sturdy in place
What I Like
- Secure zipper keeps critters and debris out
- Thick, waterproof material that stands up to weather
- Helps keep water temperature steadier overnight
- Easy to put on and remove by one or two people
- Neat, tailored look—better than loose tarps
- Low maintenance—just wipe or hose off
What Could Be Better
- Only available in one size—measure carefully before buying
- Zipper can stiffen in very cold weather; occasional lubing helps
- Not completely airtight—some evaporation still occurs in hot sun
My Recommendation
If you own a 100-gallon tank and want lower upkeep, buy this cover. The MQLD Rubermaid 100 Gallon Waterproof Stock Tank Cover with Zipper is best for people who value convenience, protection, and fewer water changes. It works well for backyard cold plunges, livestock troughs, and portable hot tubs. I recommend it to riders who keep troughs in open paddocks, homeowners with exposed plunge tubs, and small-farm owners who want less debris in water.
| Best for | Why |
|---|---|
| Cold plunge users | Keeps water cleaner and reduces heat loss overnight |
| Horse & livestock owners | Prevents debris and stabilizes water quality |
| Backyard owners with limited storage | Easy on/off zipper and compact storage when folded |
Alternative Products You Can Consider
- Heavy-Duty Waterproof Tarp Cover (100 gal) — A cheaper option if you only need a basic waterproof barrier. It won’t zip or insulate, but it’s flexible for varied tank shapes and easy to replace.
- Insulated Neoprene Stock Tank Cover (100 gal) — Better at thermal retention than a simple fabric cover. Good if you prioritize keeping water temperature stable, but expect higher cost.
- Commercial Rubbermaid Tank Lid (custom-fit) — A rigid lid option for long-term protection. It offers the best debris exclusion, but it’s heavier and less convenient to open daily.
| Product | Best For | Key Difference |
|---|---|---|
| MQLD Rubermaid 100 Gallon Waterproof Stock Tank Cover with Zipper | Balanced protection and ease of use | Zip closure, heavy fabric, insulated layer |
| Heavy-Duty Waterproof Tarp Cover (100 gal) | Budget users or irregular tank shapes | Lower cost, no zipper, less insulation |
| Insulated Neoprene Stock Tank Cover (100 gal) | Users prioritizing temperature control | Better thermal performance, higher price |
Final Verdict: Which Should You Buy?
If you want an easy, reliable way to protect a 100-gallon tank without custom fabrication, go with the MQLD Rubermaid 100 Gallon Waterproof Stock Tank Cover with Zipper. It balances durability, convenience, and protection. Choose a simple tarp if you need a very low-cost, flexible option. Pick an insulated neoprene cover if preserving temperature is your top goal. Overall, the MQLD Rubermaid cover is the best all-around pick for most users who want less mess and lower maintenance.
FAQs Of MQLD Rubermaid 100 Gallon Waterproof Stock Tank Cover with Zipper
Is this cover truly waterproof?
Yes. The fabric sheds rain well. Seams and zipper are designed to resist water, though standing water on top should be cleared.
Will this fit my oval or rectangular 100-gallon tank?
It fits most 100-gallon rectangular and oval tanks. Measure your tank and compare dimensions before ordering.
Can I leave it on through winter?
You can, but in extreme cold the zipper may stiffen. Lubricate the zipper and check occasionally. Remove heavy snow build-up to avoid stress on seams.
How do I clean it?
Wipe with a damp cloth or hose it down. For stubborn grime, mild soap and a soft brush work fine. Let it air dry before folding.
Is installation hard for one person?
No. One person can usually put it on, though two make handling quicker and easier.
