Aragonite

[DeLgAdO]

can Aragonite be as a substrate for the big freshies such as arows, oscars, devils, bichirs,etc,? it does keep the pH stable if with a heavy bioload, and its has a number of times more surface are than gravel or sand, But supposedly its only good for africans and saltwater.

Aragonite does help keep pH stable. But, that pH is in the 7.5 to 8.3 range. Your bichirs would be OK with it but, the rest prefer neutral to acidic conditions.

pH of 7.5-8.3 would be great for all the fish listed

my tap comes out at about 8.3 to 8.5 . I dont ahve and cant aford an ro unit and i dont want to use chemicals

 

[piranha45]

i wouldnt sweat it. if your tap comes out at 8.3-8.5 then so does the lfs'

 

[DeLgAdO]

lfs??? Im new to fish talk so can ya help me out??

 

[M|L]

lfs = local fish store.

I don't like to mess around with my pH, infact, I've never added anything to my tank that would alter the pH.

 

[DeLgAdO]

yea i dont like adding chem either but i intend to keep a heavy bioload and the ph will want to go down and aragonite might be just what i need to keep the ph stable

by the way, aragonite is not a chemical, its a very sepecial substrate

Yeah if your fish are already thriving in a alkaline PH then just go for aragonite.
Better yet, slowly add crushed corals.. The make good PH buffers.
