Limestone for natives in a pond

[kakojones]

I live in Florida and my friend and I are re-doing his pond. another friend has come across a bunch of limestone, is this ok for the fish? I mean I know Florida has some limestone in the ground, otherwise we wouldn't have sinkholes and we do have sinkholes.

I'm no chemist or anything and when we did the pond the first time I suggested we only use stuf we found in a pond on some of his property near the state park. I just want to know if this is the worst idea ever to put the limestone in there. I told him to hold off until I could get some info. figured I would ask here then go try to research and if i find nothing in my research I can check back here. Thanks in advance.

Well, I found something that limestone raises the PH. So now I just need to find the PH where these guys will be coming from to see if that will matter.

i would say no. limestone isnt good for your water quality at all.

lime stone is a BIG NO NO... it makes the water verry acidic and you would have to drop in pills every week this causes ph swings and causes you to have less fish., i have a waterfall thats 10'tall and atleast 20-30'long and although its three times the price i got granite insted since its a stable roch it was that or marble...

Limestone (dolomite, marble, aragonite,coral,etc.) is fine unless you want an acidic (like pH 6) biotype like Amazonia. It will tend toward pH 7.5 to 8. Organic stuff like leaves could bring it back toward pH7. It will provide good alkalinity which will make the pH very stable.
Natives like swords ,platies, mollies would do very well.
