I finally understood what was meant by buffering, that the lower pH dissolves some of the rocks carbonates which then makes things more basic.

SO I needed some good, inexpensive rock. I looked in my pets at home and the prices were mad-30 quid for a lump of marble the size of a brick!

But I just bought 25kilos of ocean rock from ebay, 20 pounds and 10 pounds delivery.

The postman didnt look very well when he got to my 2nd floor flat wih the box.

I have looked in the box and Iam delighted, there are a couple of massive bits and a good variety of smaller bits.

This is where it came from-

Good find, seems like a good price. Oceon Rock is pretty cool, Ive got a load of it and my yellow labs love it.
