You can also use limestone rocks or shells instead of dead coral rubble. A number of pet shops and stock feeders sell bags of white shells to put on the bottom of bird cages. You can use that shell too, just rinse well before use and don't inhale the dust when you open the bag. The shells are about the size of your fingernail.
I prefer limestone chip, for this sort of thing. I think it works better than crushed coral.
I know, just don't really know where to buy it here in aus.
So I'm gonna be using sponge filters, so ill have to put the limestone chips in a media bag somewhere close to the sponge filter. I'm gonna use equilibrium to remineralise the GH and then for the KH, will the limestone chips or shells act the same as coral rubble, or is there one of these three that would work the best?
Most pet shops in Australia that sell marine fish will sell bags of dead coral rubble. However, shells, limestone and coral skeleton are all made from calcium carbonate and do exactly the same thing. Limestone and shells are much cheaper than dead coral rubble.
If you live near the coast, go to the beach and look for some limestone rocks. They are cream or white coloured and most of the groins are made from limestone rocks. Just find a few pieces that are the size of your fist or double that size, and are not in the water. take them home and hose them off and put them in the tank.
Limestone is a reasonably soft rock and you can drill, cut or grind it to make different shapes or put holes in it. You can even cut it into sheet and make bridges, etc.
Just use safety glasses and a dust mask when cutting, grinding or drilling it, or use a wet saw/ grinder to stop the dust.

Safety first!. Thanks for the suggestion. Ill probably use limestone of the shells. I think that will pair nicely with seachem equilibrium. Thanks for you help.
Hi again. Would Petbarns aviary shell grit do the job for kh/ph, or would the whole shells be better?
I have no idea. Can you post a picture of the shell for me to see?

As long as there are no oil, chemicals or additives in the shell grit, it will be fine, but it's very expensive. I used to buy 20kg bags of white shells for $6.00. If you can find bags of white shells, they should be a lot cheaper than shell grit.
Rinse the shell under tap water before using it in an aquarium.

Ill see if I can find some
Settled on this. Sounded like what you described with the finger nail size. Hope they will do the trick
