Hi there,

I was wondering is it safe to use large rocks from the beach to use in my tank? i have 2 large blue dolphins, yellow lab, sailfin pleco, upside down catfish and another catfish i am unsure of his name.

I live opposite a beach on the south coast of england and the rocks over there are ideal for using in my tank but i do worry about the salt or any other nasty's on them.

Does anyone have any ideas as to what is the best way to clean them etc.. and wether they would be safe to use?

Many thanks
emily
