## Questions & Answers

**Q: Is this a roughly standard size grain size? similar to beach, sand or much larger? like twice as large? or 10x as large?**
A: It is like beach sand.

**Q: Will this substrate work if your trying to grow live plants? Like does it have all the ingredients live plants need to be healthy?**
A: No.  Try SeaChem Flourite Substrate. You don't have to replace it and I think it looks great in a planted aquarium.  You can mix it with other substrate if you want, as well. Or you could go another route, choose this substrate, if your heart is set on it, and feed your plants with SeaChem Flourish tabs.  I've done that as well.  Keep in mind though, using a light colored substrate and Flourish tabs can darken spots in the substrate.  By the way, I don't work for SeaChem.  I just used their products for years and they haven't failed me yet.

**Q: Is this for saltwater fish**
A: The description says suitable for most freshwater environments - since they made a point of saying freshwater, it sounds like it’s not suitable for saltwater, but I only have freshwater tanks so I don’t have any experience with saltwater.

**Q: Is a 5 pound bag enough for a 5 gallon tank?  I just got a 5 gal fluval spec.**
A: Yes, it's just the right amount, we have this aquarium. Aqueon 17774 Mini Bow 5 Gallon Desktop Aquarium Kit.

### ⭐⭐⭐⭐⭐ Beautiful Substrate
*by C***I on June 29, 2014*

There are two versions of the Crystal River Sand from Caribsea. One is just the sand. The other comes packed pre-cultured with nitrifying bacteria.The version that comes pre-cultured with nitrifying bacteria will come in the same plastic bag, but the sand will be moist. And it is not recommended that you rinse it out. Within the bag, you will find two small packets. One is a dechlorinator. The other contains a floculant, to help clear cloudy water. If you are starting a new tank, this is the one that I would recommend. It helps eliminate deadly ammonia spikes. Naturally, you will still want to start with hardy fish until the tank stabilizes.This is a beautiful substrate. The grain size will range from fine to medium. The size is large enough that you can vacuum the bottom without losing too much of your substrate in the siphon hose. This is the ideal size, in my opinion, for most situations. The grains are small enough so that fish feces and other debris cannot work their way into the substrate. And yet, large and heavy enough not to get too much of it get siphoned out during tank maintenance. Some fish species, like Corydoras and German Rams prefer a fine, sand substrate like this."Crystal" comes from some small, clear grains that catch the light and actually shine. Almost like a sparkle, but not bright. You can use this in a fish-only tank or you can even use this as the substrate for a planted tank. This could very well be the perfect substrate, except for one thing. If you have bright lights, algae will grow on this sand. And that ruins the beauty of it. Darker sand still grows algae, but hides it.Bottom line. If you can keep your tank clean, this is perfect for you. If you are slack on maintenance, pick a darker sand. There is a black sand from the same manufacturer called Tahitian Moon. It is slightly finer and it hides algae very well.Oh, and one other thing. If you keep rainbows, they will tend to exhibit their best colors when their sand is dark.Update: I bought a five-pound bag to replace the small amount that I lose through the gravel vacuum hose during each water change. Some will leave the tank when you get rid of unwanted plants too.

### ⭐⭐⭐⭐⭐ Follow the directions. Beautiful addition to my tank.
*by L***A on November 10, 2020*

I received this aquarium sand yesterday. I bought it primarily because I purchased five assassin snails and the love sand. I have a 50 gallon established freshwater tank. I already have soils and gravel at the bottom for my live plants, but assassin snails need sand, and this sand had great reviews. Cleaning it was easy and I just followed the directions on the bag. Waited 30 minutes for the sand to settle before reintroducing the fish to the aquarium. My Corydoras are having a field day! I am infested with mystery snails, so I’m excited to see if assassin snails help with the population and love seeing the pretty sand in my tank. Highly recommend.

### ⭐⭐⭐⭐⭐ love this sand
*by A***R on March 24, 2022*

I bought this sand for my kuhli loaches for hiding. I did half gravel and half sand. I loved the sand so much I did the entire tank with sand. I used two bags for a 20 gallon but am ordering more. It didnt make the water cloudy the first time and a tiny bit cloudy the second time but cleared very quick. I opened the bag put it under the water and poured the sand it. Helped eliminate clouding and easier to control. very pleased with this sand
