    • Beautiful Substrate
Pattern Name: Crystal River Size: 5lb (Pack of 1)
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. ... show more

    • It's sand!
Pattern Name: Crystal River Size: 20lb (Pack of 1)
I got the 20 pound bag for a 30" x 13" x 18" 29 gallon tank. With about half an inch or so covering the bottom I still have 1/3 of the bag left. I had no issues with it clouding the water as the instructional method of cutting the corners and flushing it with a hose worked really well. I kept the bag in a large bucket while filling it and stirring it with the hose. Once the bucket was nearly full of runoff water I poured the excess water in the bag out and repeated the process. I did this 6 or 7 times. There was only about a teaspoon of loose sand in the bucket. Another thing that helped was how I placed the sand in the aquarium. The tank was already populated with fish so I didn't want to just pour the sand in over them. I scooped the thoroughly rinsed sand out of the bag and gently poured it in just a few inches from the bottom. No cloudiness. I didn't even bother with the included Bio-Magnet Clarifier. It looks great. ... show more

    • Perfect for my betta!

I wanted to switch from gravel to an aquatic sand for my betta fish after having several pumps ruined by sucking tiny pieces of Rick into them. Sand seemed like a great option and after lots of research I settled on this! Overall is really beautiful, doesn't have issues with floaters or dust particles, and looks beautiful! It's much much cleaner looking and he seems to enjoy it (the betta fish). My tank is almost 4 gallon, so this 20lb bag will last him forever. Very happy with this purchase and the overall quality of this fresh water sand. Highly recommended! ... show more

    • Pretty crystal sand for my fishes.

Sand is beautiful. A bit beige mixed with white, but the crystals are still very pretty. A bit hard to wash without a hose, but a good few rinses in a bucket like washing rice, helped. Just don't dump the water in the drain as its bad if sand is stuck in the drains! I toss the cloudy water into the streets instead. I like the extra little packet of bio-magnet clarifier. It helped the water clear up faster. Nice touch. This filled a fair thin layer over half my elongated 35 gallon tank. You can see in photos. I will need 3 more bags if I want a thicker 1 inch layer to fill my entire tank. Luckily, half looks pretty enough. I have not tried cleaning it yet, so a bit worried that sand might get sucked in my pump. Guess I'll know on cleaning day. Hope it works out. ;) ... show more

    • Great Sand(but be sure to rinse)
Pattern Name: Crystal River Size: 20lb (Pack of 1)
The sand is great, a nice natural color and extremely soft, so its easy for my guys to dig around in--much better than the gravel I replaced. But again, it is very important to rinse the sand to save yourself a lot of trouble in the future. I got 2 20lb bags and I rinsed it in 3 buckets, until the water was clear and then some to just be sure. This wasn't a brand new tank, I added the sand while the fish were still in there so I wanted to avoid any issues. Sand went in without a hitch, I didn't use the included clarifier as I like to limit the chemicals going into my aquarium. I ran a water polisher for a few hours and the tank is crystal clear. ... show more

    • It was very easy to clean
Pattern Name: Crystal River Size: 20lb (Pack of 1)
It was very easy to clean. I took the end of my hose and did like the instructions suggested: cut two holes in top of bag at either end, and stuck one end of the hose thru one hole deep down and turned on the water. Eventually, I just stuck my faucet wand (unscrewed the wand part) right into the bag). It only took a very small amount of rinsing before it ran clear. There was minimal cloudiness once I put it in the tank. I started doing it with a lemonade jug but ended up just pouring it in with the bag. No problems with the fish, at all. I put a good amount in my 29g, enough for real and plastic plants to be covered well and still had enough to put a thin layer in my 55g. I usually only keep bare bottom tanks, so I only wanted enough to just cover the bottom without it being deep. So one bag worked for two tanks. 40 would've been over-kill, despite 1.5-2 20lb bags being suggested for my 29g. Within 30 mins the 29 was completely clear and the 55 never wasn't. Very pleased, it looks great. ... show more

    • Very nice sand
Pattern Name: Crystal River Size: 5lb (Pack of 1)
At first I didn't like the color of this sand inside the bag, but once I got it in my tank it really gave it some personality. The color is just right, it looks natural and my fish really seem to enjoy it. Must be washed and rewashed, and washed one more time for good measure to get most of the dust and floaties out, but otherwise it's pretty great. 10 pounds/2 bags filled the bottom of my 20 gal long, despite how small the bags appeared at first. Great product, will be purchasing more in the future. ... show more
