Onyx Sand™ is a naturally dark gray sand that perfectly complements and enhances the appearance of any aquarium. It provides not only iron and other minerals but supports optimal KH levels for freshwater planted aquariums. Being carbonate rich, Onyx Sand™ provides an advantage to any plants able to utilize bicarbonates. Although ideally suited to planted aquaria, it may be used in any aquarium environment. Onyx Sand™ is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels. Gravel modifiers such as laterite are not necessary. Onyx Sand™ is not chemically coated or treated but does have a slight buffering capacity that may raise pH by 0.1 - 0.5 pH units (depending on source water characteristics). Onyx Sand™ is good for the life of the aquarium and need not be replaced.
Pool filter sand has zero nutrients. Some aquarium plants get most of their nutrients out of the water - anubias for example

For a planted aquarium there are many good options (better than sand). Fine grade gravel looks like large grains of sand and is much less dense than actual sand. This would be a much healthier option for your plants and easier for you to care for. Most plants can do fine in medium grade of gravel (which is also considered "standard size"), which is even easier to maintain and also looks nice.

i wouldnt recomend play sand for a planted aquarium mainly because of all the air pockets that build up. all the air coming out could harm your fish wich is why i dont have fish in this tank its just a grow out tank. if anyone wants to trade plants please message me i will make another video about that. thanks!The best plants for planting in sand substrate are ones which have large root systems, thick stems, require few nutrients through their roots and grow relatively quickly .Examples of good plants for sandy aquariums are Echinodorus (amazon sword) and Cryptocoryne species. Other plants that have smaller root systems can be easily dislodged by water movement or by aquarium fish.Planting in sand substrate can be challenging but a bit of thought can really prevent or even stop aquarium plants floating away. Sand is very fine and is not the best for plants to root into and will not usually hold new plants in place, especially when the current is strong. Another issue many people find when planting in a sand aquarium is that fish really love to burrow and dig into it, usually disturbing the plants.There is a product available in the swimming pool trades. It is often quartz, sand-sized particles, that are added to the finish coat inside a pool to make it different colors. 3M Colorquartz was one of them that you will find references to. Unfortunately 3M is no longer making their product, but other companies are making similar products. Pebble Tek is one. Some of their materials have sea shells added for more sparkle. These will dissolve in the aquarium and make the water more alkaline. These quartz products are very dense and hold the plants down well. I have one of the black ones in a tank, and it looks really nice. There are other colors.No, Estes Marine Sand is inert and will not alter any chemistry in any way. This makes it an ideal sand for any tank (freshwater, saltwater, reef, planted, etc.). Unlike other silica based sands it won’t ever add silicates (which can cause brown algae problems) because of the ceramic coating. For certain tanks where a high pH and hard water are appropriate I would use crushed coral in the filter (bagged, just like carbon). True marine sands can alter the pH but then you run in to the same issues as many non-aquarium sands (wrong grain size, grain size isn’t uniform, etc.). Coarser marine substrates like crushed coral will just trap a lot of debris, just like gravel, so it is still more maintenance than necessary.Play sand is something I have always considered a no no in a freshwater aquarium. There is never a way to know how heavy the mineral content is with it, and the grains tend to be very fine, which creates mud on the bottom... thus organic breakdown that can cause problems for the animals. If sand is absolutely needed, silica sand is the best and safest option. You should be able to purchase it at any lfs that sells gravel and other specialized plant substrates, or at most reptile supply stores. If its not seen on the shelf, you can ask for it. Some lfs's don't stock it regularly because there is such a low demand for it in most areas, but it should be easily available to them through their distributor.
