## Description

Carib Sea ACS00050 Aragonite Reef Sand for Aquarium, 40-Pound

Review: Fine. It's sand. It's fine sand. It's fine, fine sand. In fact it's fine fine, fine sand. Whatever. I like it. - A very nice fine, white sand (the online picture looks much pinker than it actually is, at least on my screens.) I use it in multiple tanks with medium-to-deep sandbeds. It's not so bright that it pulls your eyes to it yet gives a very nice contrast to dark rocks, desired algae and colorful corals. With a deep sandbed you will definitely see the various colors of the underlying algae against the glass or acrylic. I prefer a very natural look and I'm very pleased with it. My burrowing starfish and snails also enjoy it; easy to "sink" in to and no sharp edges. Creatures that actually try to create burrows will have a challenge...but hey, what else do they have to do? Its pretty enjoyable watching shrimp, gobies and pods do constant home maintenance instead of doing some myself. Cons(?) 1. Any significant flow over or at it WILL move it around. But as long as you’re not limited to pushing high flow low in the tank, then once it's settled it's no problem. I set up the rockwork and use a varying speed pump in one tank to intentionally give some slight sand movement in little pockets and it adds to the look. 2. if you and/or your clean-up-crew are not diligent, built-up detritus will stand out. Not sure this is a con as long as you're good about tank maintenance. 3. The ony "real" con in my book: you dont HAVE to rinse it...but, if not, expect complete cloudiness for a number of days. I do give it a fairly thorough rinse and I still end up with cloudiness for a number of hours. But see below. Suggestion: if you want to be precise where the sand goes and almost eliminate the cloudiness issue, - get a gravel cleaner that is approximately as long as your tank is deep - remove the tubing so you have just the gravel cleaner tube and the cap that attaches to the tubing. Make sure the cap is on tightly. - turn it upside down and let it fill with water so that you're not fighting bouancy - depending on the diameter of the tube you can either scoop the sand directly in to it or use a funnel - the sand will exit slowly through the hole in the cap. Move the tube around and use it like icing a cake. Its a slow process but the sand goes where you want it - the remaining cloudiness will stay in the tube. If you remove the tube right away you'll still get some cloudiness in the tank. Or you can leave the tube in the tank a few hours and most of what is causing the cloudiness will eventualy sink. - Orrrrr...if you're in a position to do so and feeling brave, cover the top of the tube to create a vacuum. Lift the tube, cloudy water and all, out of the tank. Just be sure to have somewhere close by to dispose of cloudy water.
Review: great sand great value for the money - this is a great product at a reasonable price for live sand that you do not have to rinse before you use, settled quickly in the tank, i added more sand to an already established tank and it did turn the water milky but lke i said it settled quickly and my fancy goldfish love playing in it. would recommend to any fish enthusist

### ⭐⭐⭐⭐⭐ Cheap for the size and worked fine
*by G***E on October 8, 2024*

I used this sand for a 8g rectangle aquarium mixed with a plant substrate for nutrients. I had to wash it out at least 10x, until the water was cloudy, but not milk colored. However, they have a lot of sand for a good price. The sand is a nice cream color, which looks good and makes the dark gray rocks stand out. The plants are doing well and the betta, Wonder, is also doing good. The first day it was cloudy, but it got better fast and by the third day, the water was crystal clear. I am happy with this sand, and would buy again if I need more for cheap. Thank you Petco!
