Hi, done a bit of research and decided sand would be better for my froggies than gravel (I was given them, and this is what they had been kept on for years), however I've looked in local shops so it will have to be bought online, so I can't look and see the size, sharpness etc. Can anyone give a UK link for a sand that they would recommend?

Also, I have never used sand in any of my aquariums. I'm assuming using a gravel cleaner for water changes would just suck up sand? May seem a silly question, but how do you keep it clean?!

Thanks
