I have been investigating different types of sand substrate to use in my catfish tank. Someone has suggested Pool Filter Sand. Has anyone used this in their tanks and is it safe?

I only use sand designed for marine tanks.Only my marine tank has a sand substrate.

I use CC...in my tank and Sand in my Refugium.... it is marine quality sand.... South down works well, and some play sand is fine also....

I bought some sand and it says on the bag 16/30 Grade. Is this ok to use?

What type of sand is it?? And where did you get it??? Is it pure sand or construction grade???

It's Pool Filter sand. The guy at the pool shop said it was natural sand which is a certain grade suitable for pool filters. No chemicals or any other stuff in it. He said it's safe to use in aquariums. I just need to rinse it a few times to get rid of the sand dust, like you would gravel. I have read on other forums that this is used in chicld tanks. I'm on a budget so I needed to find something that was not so expensive. I bought a 12kg bag for $12.95. I hope this is ok to use. I'm always worried about trying something new like this as I don't want to hurt my fish. The setup will be a freshwater tank

If there are no chemicals in the sand it should work fine...

i use marine substrate white sand.use sometin that is precleaned and made for aquariums

When I started up I used sand that was bio cured and then a bag of reg marine sand, this way it gave the tank a boi boost

I got the old southdown sand and seeded it with some sand from one of my other tanks.... Worked great....nice sand also!!!! The grains were suggar sized....the fauna and sand critter life love that size grain....
