Freshwater Sand? Safe or Bad?
Hey! Was wondering if I would be able to use freshwater sand for my 55 Gallon.
I'm pretty sure I can but not sure if there is any.
Does anyone know?
I'm thinking about crushing some gravel and having just spread on my tank floor.
Not sure if it's safe or not.
Anyone have any ideas?
There are sands that are safe for fresh water tanks. I have used Carib Sea products in my tanks for years with no problem. Petsmart has started to carry them but the website has a find local supplier tool if you are looking for more than one or two of their colors.
caribsea your aragonite source and more!
Lots of folks here use regular old playsand for Lowes or Home Depot. I have pool filter sand over natural gravel. You'll need to rinse and rinse and rinse some more to remove all the fine particles from the sand before putting in the tank.
Heard that sand for local hardware stores and such had chemicals in the sand that could negatively affect your fish. Does that happen to you? Or do you know anything about that?
I just started my new 55g tank the other day. I used Quickcrete play sand from Lowe's. Byron recommended it to me, it what he uses in his tanks.
9 out of 10 toddlers recommend play sand. Play sands are chemical free and should be safe ;-)
You are correct that some types of sand may have additives. And some types are not inert [inert means they will not affect water chemistry, such as hardness or pH]. Crushed coral sand and aragonite sand for instance will add calcium and magnesium raising the hardness of the water, and the corresponding pH will be much higher; this is ideal for rift lake cichlid tanks, or livebearers, but the last thing you want in a tank of soft water fish. Silica-base sand is not good to use because of the silicates (a type of mineral) which can increase the risk of diatoms (so-called brown algae). And some sands are too coarse (sharp edges).
Many of us have used playsand. It is very natural (similar appearance to many stream sands in the tropics) and is inert. Takes a lot of initial rinsing as someone mentioned, but once in the tank it performs well. Then there are the much more expensive "aquarium" sands which do look nice and perform well.
Here's a link of something I'm thinking about getting Bryon.
Would you recommend?
