Mystic White II Swimming Pool Filter Sand - 50lb Bag

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!

Arrives right at your door. Have bought a few times. Keeps pool very clean. High quality!

Exactly what pool needed. Easy to use and works

Update- 8/18/25- I wound up replacing the Bestway pump with another brand with a stronger pump and greater GPM flow rate after it crapped out on me. I stuck with this sand and it cleared the algae that had built up after a big storm within hours! This sand is still a winner and well worth the price since I’m not spending it on pool chemicals anymore! It’s a time saver and gives you more time to actually enjoy your pool! I had replaced the sand in my filter twice and the beginning of the summer after taking the whole system apart to flush it. I bought this brand as my last hope before having to purchase a new pump and quickly figured out it wasn't the pump, it was the other so called quality filter sand that was garbage! It cleared the algae bloom within 24 hours in my 6000 gallon above ground salt water pool. No more worrying about the pump burning up and it has been working very nicely with my salt water chlorinator after using this medium. I haven’t had to change the sand since putting this brand in and the pool remains sparkling clean! Seriously- spend the money to avoid the hassle of trying to correct a green or black algae bloom, it’s worth it in the long run!

If you can get over the fact you're having a 50lb bag of sand shipped from who knows where, its great. Better than driving into town an hour and a half away and spending half a day and half a tank of gas on. This is the epitome of everything that's right and wrong with Amazon. But hey, your pool or spa will be crystal clear!
