Backyard Aquaponics
A place to discuss aquaponics

does that mean that instead of using blue metal we should use marble chips (readily available her for not much more money)

maybe for those very *stylish* backyards

just imagine the glare LOL

If we agree that you cant have too much then yes

I'll take a hit for the team. Next system, the bottom half of the growbeds is marble

C'mon monya, make (what was his name? Tony?) proud and take a real hit!

100% Marble

On the plus side it will reflect alot of light to the underside of your plants and make them grow quicker! Promise!

okay

cool!

I'll take the hit with you!

Does anyone kow of a cheap source for crushed marble in melbourne?

The last time I looked, it was about $55 a tonne at the local sand and metal depot

In keeping with the touch of marble it would of course be compulsory to have your standpipes carved as columns with lions heads....

and your siphon returns as statues of archers standing on one leg or water bearing maidens .....

who's got that statue in their pond? they'd be able to have marble in their growbeds and it would look just perfect

You could try TTI stone. they make paver and stuff. Some of the that stuff is out of marble. Might even be a waste product.

I got the marble floor for my pizza oven out of a skip that came from there.

What are the effects of marble on pH/hardness. I have always heard that it is used to lower pH, below what bicarb can. I might be wrong, or it could just be a good pH buffer...

tim i think you mean raise ph.

it should have the exact effect that sea shells, shell grit or calcium carbonate powder do.

Yeah, sorry. I always look at it like a scale with one at the top (acid) and 14 at the bottom (bases). I should start saying it right.
