Substratum.

[Rinaldo Fontenele]

One more question for the comunity....

Which best substratum to use in marine aquariums?
Halimeda, aragonite, calcite, dolomite???

In my vision I prefere halimeda!

 

[Len]

Halimeda is a type of aragonite. It's great medium for substrates or calcium reactor media.

 

[Rinaldo Fontenele]

In my knowledge halimeda has fosfate therefore is a seaweed.
I don´t use as calcium reactor media!

 

[Len]

Halimeda is a fairly unique algae that lays down an aragonite (a specific calcium carbonate matrix) for its rigidity. Some of the purest aragonite are found in Halimeda.

Yes Len, I know!!!!
But, if not do a previous treatment, the residual phosfate we can be problems.

 

[Len]

To my knowledge, Halimeda aragonite is actually very low in PO4 and any other compounds. Though I'm not a chemist (not even close ), I would imagine that aragonite crystal would be low in PO4 since phosphate would hinder calcification. I do know Halimeda aragonite is often used in labs that call for aragonite, so that should say something about its purity.
