Thats not called, being cheap, thats being resourceful.sissy said:I have been using lava rock for years and love it even though some think it is old fashioned way to filter it sure works for me .I am cheap and try to save every where .I soaked mine and picked out the rougher bigger ones and the ones that floated got put in the plant pots with the kitty litter .Just call me cheap :cheerful: and proud of it .
You'd be surprised how much it costs to look this cheap!
