Rubermaid 300 Gallon Oval Waterproof Stock Tank Insulation Pool Cover, Cold Plunge Ice Bath Tub Horse Livestock Feed Water Trough Insulated Cover for Outside Polar Protector 300 Gallons Hot Tub

This is a great addition to the 150-gallon fuel tank. The husband uses it every day. A very good feature is that it can fold the upper part and then fold it up.This might be better if you used your own Amazon account to order it from!

Very sturdy thick material. It's easy to use over my claw foot bathtub. Fits perfectly.

So far, I'm satisfied. Strongly recommended.

Water proof cover is Amazon. Keep my cold water clean

This comes in its own little zipper bag and unfolds to reveal that the underside has the silver reflective layer but no actual insulation to speak of. It fit's just like it was made for the Rubbermaid 100g and has both a drawstring (which is pretty hard to get tight just due to the circumference) and a gator mouth clip on a flat nylon strap. The strap goes into four sewn loops and I would think it would a better choice than the draw string if the winds got high. Overall, well executed for its intent.

This cover is exactly what I needed for my 150-gallon stock tank! It fits perfectly and does a great job keeping debris out while also helping with insulation. I use my tank for cold plunges, and this cover helps maintain the water temperature, whether I’m keeping it cold or warm. The material is durable, waterproof, and well-made, so I expect it to last a long time. Definitely a great investment for anyone using their tank for ice baths or as a water trough. The snug fit prevents wind from blowing it off, and it stays secure even in bad weather. It's also lightweight enough to remove easily but sturdy enough to withstand daily use. The waterproof design keeps my tank clean and reduces maintenance time. Overall, I couldn’t be happier with this purchase!

So the strap that is supposed to hold it tight actually lets it slip out pretty easily. The flap that opens for animals to drink out of frequently gets blown back over, and into the water. My biggest complaint is that they didn't add any rigidity to the top (or floatation), which would have been very little extra expense and would have made the whole product better in multiple ways. I've added some photos that show how it looks after a few days of use and you get the idea.

I am happy with this purchase. My highest recommendation.
