The sand is so beautiful. You can see the pink colors. And it won’t blow away easily.I got one bag for my 25g Innovative Marine Fusion Lagoon 25g. It’s about 1/2â€- 3/4†in most parts, in some areas It’s about 1â€- 1 1/4â€.The Diamond Orange Goby can shift it with no problem. But the Two dot Goby is spitting the bigger size and the smaller or finer sands goes out it’s gills.Hope this can help.

I am using this 20-pound bag of Arag-Alive sand to provide live-sand filtration support inside of a mini-litterbox repurposed for this sand. 20# of sand provided a roughly 3" deep surface in that container, which was then placed into my open sump in my hydroponic tray grow-out tank setup. The bag came with some water conditioner to help reduce cloudiness, but I didn't need it in my case. The sand provides a great living bed for nitrifying bacteria and works great for this application.

Bought 5 bags for my 180 reef tank. saved $40 over the local petstore shipped to my door free. good heavy based sand and shell dosent look like a sand storm with all the circulation. Been in use for approx. 3 months went through a short cycle of high phospates. All looks great now

This is just a blatant scam. I’ve bought many bags of the Bimini pink live sand in the past and I knew immediately when I took this bag out of the box that it was NOT Bimini pink. On further inspection I found two blue stickers on the bag, as seen in the photo. One sticker covered up the original barcode printed on the bag and the label “Bahamas oolite.â€The other blue sticker said “best if used by December 2022. That sticker covered up the original “best by†date of December 2021, again as seen in the photo.

This sand came in perfect condition. Doe I Had problems with the fish tank leaking and had to remove the sand into a 5 gal.bucket for three weeks until I got a new tank, the live sand survide for the tranfer. It looks great in my new tank and thefish keep sending me kisses for the larger tank.

Great product. Helps to cycle new tanks faster. Only issue I had with product description was that it didn't identify grain size. May bag was course sand, which means it is smaller than crushed coral and large enough that it doesn't get sucked up when vacuuming the bottom during water changes.

I like this sand. There are a variety of grain sizes, and yes some are huge. I don't personally like the larger chunks so I pull them out when I see them. But in general the sand is very pretty to look at with lots of texture and color. I haven't had a problem with it blowing around either.
