A new subtrate

I've been having trouble with the soil that I get no matter where I get it I'm finding bit's of rubble or plastic etc in it. So ive decided to change what the tortoises have in there tables. After researching it what I found to be more cost affective aswell as easier to move around was Coco Coir. I bought a large bail that when it turned up wasnt as large as I thought. I put the 60 litre bail into a big plastic tube and filled it with water and left it soaking over night. When I woke up in the morning ready to do the swap it had expanded massively enough to fill 3 tables. One thing I like is its not a dirty subtrate it just washes off your hands easily that combined with its ability to hold water make it superior in my opinion. The tortoises love it and all I have to do is every 2 or 3 days pour about 3 litre's into it and move it around which keeps it moist and the tortoises happy. Coco Coir doesnt have any pieces or rubbish in it so is safe.
