What is a breeze block made out of? We (USA) often call a cement block a
brick. So if your breeze block is cement, yeah, that's what many use. In a
small pond a fresh block can raise your pH, so many use a plastic crate or
basket. ~ jan

I know that you should stand the pump on something to (hopefully) keep it
out of the silt and the most common thing for this purpose seems to be
bricks. Well, I haven't got any bricks to hand but I have got a couple of
breezeblocks; are these safe to use? Are there any chemicals that could
leech out or any other reason why I shouldn't use them? Or should I just get
a couple of bricks?
