Breeze Blocks In A Fish Tank

[Miss Wiggle]

could be wanting to mimic the fish's natural environment, most river fishes from the UK will be most at home among trolleys, bikes, bricks and other assorted rubbish!!

lol we may all go and get trolleys for the tanks would be...different lol

I'd say if you got a breeze block and painted it like a dark colour and attached some ricca to it...it would look pretty neat in a big tank

here is a breeze block for those that dont know

actually that is a Concrete masonry unit (CMU) not a breeze block
this is a breeze block

and this is a cavity breeze block

Breeze blocks are no longer used in the UK. They are called either light weight building blocks or Aerater concrete blocks.
Breeze was a waste ash from power stations and used in early UK blocks many decades ago.
Because breeze blocks have a low compressional strength, they are no longer used but you can still find them around if you look hard enough

To us in the US, all of those are CMUs. The first one is an 8x8x16 or 200x200x400 in metric. The second solid one looks like a 4" solid or cap block (4x8x16) and the last looks like a 4" regular at 4x8x16. With my dad and 2 uncles being masons, and haing worked construction with them for over 15 years, I have handled a many of them. Also sold a lot when I worked at the block company which was actuallypart of an English company: RMC. I still don't know why anyone would want one in their tank or why they thought it would float.

as for the stuff the blocks might put in the water, you just have to look at the run off water under a pack of blocks on any building site, to see the amount of crap that is washed out, even after they have got wet several times. if you must use them, seal it first!

well many modern blocks will float, at least at first. the very reason these new blocks are used it for insulation, they are full of air!. most people can carry 4 or 5 of these things now, the restriction on how many is the bulk not the weight.

There aren't any that I've ever used that will float and those are the lightweight and feather-lite block. Even with the air and lightweight material (the aggrigate used in them), they still sink like a rock. And you're right about all the stuff that comes out of them. Lime is the main thing. When you see a block wall somewhere that has white stuff running down it, it is usually the lime from the blocks and the mortar used to lay them. And over time the cement will also wear away.
