"Great substrate."

Not too white, more a beige-grey color. Color in the pic looks pretty true to the real thing. Good thing I'm not in a rush so it will have time to settle. The Estes sand came highly recommended. The light color is really pretty and makes it easy to spot various critters. 10 weeks in and I have four tanks going. Cleaning it was easy and I just followed the directions on the bag.

Seachem 3525 Final Thoughts

"I have no complaints."

But if you want actual fine sand might not be what your looking for. Then swirled and dumped what didn't sink immediately. The water was clear by the next day. I received this aquarium sand yesterday. It's absolutely beautiful and I'm very pleased with it. The sand looks more natural and clean. If you get this sand rinse it, I cannot stress that enough, rinse it.

"More like micro gravel."

Color in the pic looks pretty true to the real thing. But like everything else, you have to make choices and compromises. It is slightly finer and it hides algae very well. Dont force yourself to look at a boring bare bottom tank! Highly recommend, found out about it on YouTube. I love this substrate, I use it for my betta& goldfish tanks and it looks great. I did lots of research on the subject and decided to make the leap.

Seachem 3505 Final Thoughts

"Will purchase again."

I've had it in my aquarium now for just about 24 hours and cycling. The grain size will range from fine to medium. All three are inert; therefore, they do not affect ph. Use the strongest, most focused nozzle you have. No need to rinse before putting in aquarium. Take my advice, which I got from someone else, and buy a mini gravel vacuum. I think it's probably OK to use without any washing, as it says on the bag.

"He digs holes."

The sand arrived dry, I'm still unclear if that's how it was supposed to arrive. If you can keep your tank clean, this is perfect for you. Used to have a dark substrate but decided to change to this. Just be smarter than me about it and you'll be very happy with the product. It looks great and it's super quality. I have yet to do a water change, but I do not anticipate any problems. Kind of sharp sand, not the soft smooth kind.

"Sand is beautiful."

I bought the Sunset Gold color and it is a beautiful sand. This sand is almost exactly like the beach in Destin, FL. Mine play and frolic constantly, leaving happy little trails all over the tank. Will never use ugly waste trapping gravel again! This torpedo beach sand is wonderful. It has cleared up but still a little cloudy. The grain size will range from fine to medium.

"No complaints at all."

But like everything else, you have to make choices and compromises. Was frustrating but nobody's fault but mine. I went ahead and used it without rinsing it, which was a mistake. Then swirled and dumped what didn't sink immediately. I'm probably only going to use this brand from now on. Dumped sand in bucket and let water overflow get rid of the floating stuff. It's absolutely beautiful and I'm very pleased with it.

"Just some dust."

This is the easiest sand and gravel I've ever cleaned. Really nice appearance in the tank, looks very authentic. Plants are easy to plant in it as well. If it clears up I'll try to remember to do an update review. This sand is nice and heavy, and has a nice shine to it. My goldfish seems much happier and will dig and siphon the sand. I toss the cloudy water into the streets instead.

"Really good sand."

If you are starting a new tank, this is the one that I would recommend. Come to find out the sand is somewhat dirty. It's as close to white sand as you can get! I used to use the bigger gravel, but wanted to change it up. I received this aquarium sand yesterday. Use the strongest, most focused nozzle you have. I bought the Sunset Gold color and it is a beautiful sand.

6. AquaNatural Oolitic Aragonite 20lb Aquarium Sand for Reef, Saltwater and Marine Tanks and Aquariums

AquaNatural ARAGO020 First Impressions

"No complaints at all."

I used about 9 lbs in my 5 gallon tank, since I wanted a deep substrate layer. Like I said earlier, it's like beach sand. Bought this 50lbs bag for my 55g freshwater aquarium, boy is the white sand nice! Half of the bag was more than enough for my aquarium. I still love it and maybe will return to it someday after my aquarium is settled in. Plant tanks require high light levels. This could very well be the perfect substrate, except for one thing.

"This sand is very fine."

The other comes packed pre-cultured with nitrifying bacteria. We used regular tap water and water from our main tank. The item is as pictured and described. This sand is beautiful and incredibly soft! You'll be shocked at the fine particles that come out! This sand is almost exactly like the beach in Destin, FL. Naturally, you will still want to start with hardy fish until the tank stabilizes.

"HOW TO WASH SAND."

I unloaded it into a bucket and continued to rinse several times. Highly recommend, found out about it on YouTube. I found that red cherry shrimp adore diatoms. My beautiful sand turned a very dark brown. This is a nice color of sand and looks good under the light. It has cleared up but still a little cloudy. Kind of sharp sand, not the soft smooth kind.

"Shrimp tank."

Have a seat and shoot the water with force down into the sand. It helped the water clear up faster. My beautiful sand turned a very dark brown. I bought the Sunset Gold color and it is a beautiful sand. You probably need more if you are planning on planting live plants. The Estes sand came highly recommended. For a Flounder tank, well, we will just have to see when they get here.

"Worked beautifully."

Clear water, no chemical issues and makes the tank look sparkling clean. The filter doesn't agitate the sand either. Plants are easy to plant in it as well. I'm probably only going to use this brand from now on. The Estes sand came highly recommended. And it is not recommended that you rinse it out. It helps eliminate deadly ammonia spikes.

"It is a very fine sand."

The bag is small, but the quality of sand is good. Darker sand still grows algae, but hides it. The bag is small, but the quality of sand is good. I'm setting up another tank and this will be the substrate. Good thing I'm not in a rush so it will have time to settle. Not as thin as sand but works well for our musk turtle substrate.

This sand is beautiful and incredibly soft! If you have bright lights, algae will grow on this sand. If you are starting a new tank, this is the one that I would recommend.

"Like a dog."

At that point rinse the sand a couple more times. The other contains a floculant, to help clear cloudy water. The sand looks more natural and clean. It's as close to white sand as you can get! The bio magnet clarifier clears the water up at first, but then it gets cloudy again. The soft sand makes it easy to place plants without damaging them. You really can't go wrong buying this sand!
