However, it is normal for aragonite sand to contain small dark colored natural mineral particles.) For optimal results, it is recommended to rinse the sand briefly before adding into the tank. #### Follow Us ![](https://maxspect.com/media/yootheme/cache/b3/qrwechat-b3c09905.png) - [](https://www.facebook.com/Maxspect) - [](https://www.instagram.com/maxspect_ig/) - [](https://www.youtube.com/@MaxspectOfficialChannel) - [ EN ](https://maxspect.com/en/nano-tech-bio-media/1120-bio-sand.html) - [ ES ](https://maxspect.com/es/nano-tech-bio-media/1137-nano-tech-bio-sand.html) - [ PT ](https://maxspect.com/pt/nano-tech-bio-media/1141-nano-tech-bio-sand.html) - [ FR ](https://maxspect.com/fr/nano-tech-bio-media/1135-nano-tech-bio-sand.html) - [ IT ](https://maxspect.com/it/nano-tech-bio-media/1138-nano-tech-bio-sand.html) - [ DE ](https://maxspect.com/de/nano-tech-bio-media/1136-nano-tech-bio-sand.html) - [ PL ](https://maxspect.com/pl/nano-tech-bio-media/1133-nano-tech-bio-sand.html) - [ 日 ](https://maxspect.com/ja/nano-tech-bio-media.html) - [ 简 ](https://maxspect.com/cn/nano-tech-bio-media/1134-%E7%BA%B3%E7%B1%B3%E7%8F%8A%E7%91%9A%E7%A0%82.html) - [ 繁 ](https://maxspect.com/hk/nano-tech-bio-media/1131-%E7%B4%8D%E7%B1%B3%E7%8F%8A%E7%91%9A%E6%B2%99.html) #### Products - [ Professional Series ](https://maxspect.com/index.php?option=com_content&view=category&id=92&lang=en-GB) - [ Innovate Series ](https://maxspect.com/index.php?option=com_content&view=category&id=93&lang=en-GB) - [ Jump Series ](https://maxspect.com/index.php?option=com_content&view=category&id=94&lang=en-GB) - [ Coral Tools ](https://maxspect.com/index.php?option=com_content&view=category&id=95&lang=en-GB) - [ Nano-Tech Bio-Media ](https://maxspect.com/index.php?option=com_content&view=category&id=96&lang=en-GB) - [ Lagoon Series ](https://maxspect.com/index.php?option=com_content&view=category&id=97&lang=en-GB) - [ Smart Aquarium ](https://maxspect.com/index.php?option=com_content&view=category&id=205&lang=en-GB) - [ Accessories ](https://maxspect.com/index.php?option=com_content&view=category&id=86&lang=en-GB) #### Firmware Updates - [ Product Manuals ](https://maxspect.com/index.php?option=com_content&view=article&id=890:product-manuals&catid=202&lang=en-GB) - [ Mobile Apps ](https://www.maxspect.com/en/?view=article&id=880:mobile-apps&catid=202) - [ Firmware Updates ](https://maxspect.com/index.php?option=com_content&view=article&id=870:firmware-updates&catid=229&lang=en-GB) #### Press Releases & Patents - [ Press Releases ](https://maxspect.com/index.php?option=com_content&view=category&layout=blog&id=87&Itemid=1157) - [ US Patents ](https://maxspect.com/index.php?option=com_content&view=category&layout=blog&id=98&Itemid=1158) - [ European Patents ](https://maxspect.com/index.php?option=com_content&view=category&layout=blog&id=99&Itemid=1159) #### About Maxspect - [ About Maxspect ](https://maxspect.com/index.php?option=com_content&view=article&id=102&Itemid=1160) - [ Contact Us ](https://maxspect.com/index.php?option=com_content&view=article&id=103&Itemid=1161) - [ Login ](https://maxspect.com/index.php?option=com_content&view=article&id=735&Itemid=1220) - [ Register ](https://maxspect.com/index.php?option=com_users&view=registration&Itemid=504) ##### Cookie Policy : - [ UK ](https://maxspect.com/index.php?option=com_content&view=article&id=516&catid=203) - [ US ](https://maxspect.com/index.php?option=com_content&view=article&id=515&catid=203) - [ CA ](https://maxspect.com/index.php?option=com_content&view=article&id=514&catid=203) - [ EU ](https://maxspect.com/index.php?option=com_content&view=article&id=512&catid=203) ##### Privacy Statement : - [ 简 ](https://maxspect.com/index.php?option=com_content&view=article&id=520&catid=203) - [ UK ](https://maxspect.com/index.php?option=com_content&view=article&id=519&catid=203) - [ US ](https://maxspect.com/index.php?option=com_content&view=article&id=518&catid=203) - [ CA ](https://maxspect.com/index.php?option=com_content&view=article&id=517&catid=203) - [ EU ](https://maxspect.com/index.php?option=com_content&view=article&id=513&catid=203) ##### [ Google Play Data Safety Section ](https://www.maxspect.com/en/google-play-user-data-safety-section/1092-googleplay.html) ##### 公安备案号：44011302002470
