Works perfectly in an aquarium and costs much less than the small bags of sand!
The best sand for aquariums! I bought the other more expensive brands, and one of them was so dusty in the tank that it never cleared up in a month, and I pulled it out and tossed it, and put this in! Then I put this sand in all of my tanks. I've used gravel for 30 years of fishkeeping, but switching to sand has given me new stuff to learn and makes lots of fish happier! My African cichlids spit this stuff at each other! I rinsed it thoroughly, but found little debris and it sinks and stays there, not dusting the aquarium! The color is the same white/beige color of the sand in the small bags, only this stuff costs 1/4 as much! I was hesistant to try it, but the facebook fish groups all said to try this and I'm glad that I did!

You will love the Quality!!!
This is the perfect sand for your filter. I had been battling my pool for weeks. I purchased this and the pool was crystal crystal clear in a day. The quality is superb, no need to sift out gravel and it gets the job done. It’s the perfect size to fill my filter and will last me a very long time. Thanks for saving my sanity 😊

Very good product with good customer service.
Sand works perfectly, and customer service is great. We use it for our fish tanks and the color matching a white beach sand.

Effective
This is really effective filter sand. I use it in my Intex sand filter and it does a great job. One bag was plenty to fill up the filter and lasted for several years. It was probably still good, but I went ahead and just replaced it so it will be fresh and ready for when I open the pool next season.

Good quality
I tried using the "filter balls"...mistake! After learning my lesson I decided to go back to sand. I wanted a good clean sand, and this looks to be nice and clean. My pool is clear again. I will just be glad when the smaller particles quit blowing thru to the pool.

Worked perfectly
Although I only needed one for my pan steps, I kept the other for a back-up

⭐️⭐️⭐️⭐️⭐️ Crystal Clear Results – Reliable Filter Sand That Works
I’ve used a few types of filter sand over the years, and Mystic White II stands out. After switching to this sand, my pool water looked noticeably clearer within just a day. It works great with my above-ground pool filter pump and keeps debris and fine particles under control. The sand is clean, uniform, and flows well through the system without clogging. It’s also easy to pour and manage during maintenance. Definitely a must-have for anyone serious about keeping their pool sparkling and low-maintenance all summer long.
