![]() Even though it already came pre-washed, there is still a considerable amount of dust inside the bag. The only issue I had with this product is how dusty the contents are. The color of the fish just contrasts really well with the substrate. In addition, the brick-red color makes it one amazing option for the most suitable substrate for Oranda goldfish. The earthy color makes it look more natural, especially when you have a couple of plants in your tank. I also like the brick red color of this gravel substrate. The addition of waste from the goldfish will only make it better. ![]() This already contains enough nutrients and minerals to help the plants establish themselves. ![]() If you are starting a new tank, you just need a thick enough layer of this substrate then start planting. It does not need any additional gravel modifiers. This substrate also works well on its own. If you already have an established aquarium, adding this substrate will not botch up the water chemistry. With that said, this will not help balance the pH level of the aquarium at all. The particles are small, and would also compact a bit after a while, so the plants’ roots can take hold easily.Īnother thing I liked about this product is that it is not chemically treated, so it will not affect the pH level of the tank’s water in any way whatsoever. Fluorite is a naturally-occurring mineral, and it is great for planted tanks because it behaves just like loose soil. If you are thinking of starting a goldfish tank with live plants, I highly recommend using this substrate. This may seem like a bother for most people, but this one extra step can prevent a lot of problems. I try to avoid problems with parasites by boiling new substrate for a couple of minutes to kill any parasites that might be in them. It took my tank less than a week to normalize its pH level and it has not spiked up or down ever since.Īlthough it did not happen to me, I have read reviews that their batch of crushed coral substrate contained parasites. They can also lower the acidity of the water. If you are having trouble with the pH balance of your tank, you can add this substrate. This substrate works quite well as a biological filter, thanks to the large surface area of every particle.Īnother reason why I love using this product is that it also helps balance the pH level of the water. It would be like what you would be doing with any other filter media. I just need to place the substrate material into a filter media bag and then put it inside the filter housing. ![]() The more surface bacteria there are, the better it will be at neutralizing nitrates and ammonia.Īnother thing that I liked about this substrate material is that the particles are large enough that I can use them as filter media. It is also an indication that there are plenty more surfaces where beneficial bacteria can grow. Still, just like a normal aquarium gravel substrate, you should rinse this thoroughly to get rid of dust and dirt.Ĭrushed coral is somewhat rougher than plain gravel, which means it has a larger surface area in total. However, despite being made of coral, it has been treated and desalinated, so it is safe to use even in freshwater tanks. It entirely consists of coarsely-crushed coral. ![]() This product for your aquarium is technically not gravel. ![]()
