Testing Rocks With Vinager

[Duzzy]

Hi there,

yesterday I had my hardness tested due to an unusual ph reading and it turns out it was 900 whatever, so I did water change and will do more over the next few days. I removed the rocks and will test them with vinegar today 2 thinks what happens if they are unsuitable? and is it fool proof I mean if they don't fizz could they still be a problem?

The only other things in the tank other than flora and fauna is substrate (Dupla ground) which I believe is inert and the mopani driftwood that was soaked and boiled in our town water which is very hard. Could the driftwood be leaching that hard water?

Regards Darren

Hi Darren,

I'm not sure if the vinegar test is absolutely fool-proof, but it is certainly a good test. Maybe some of the more science orientated guys can help you further.

With regard the Mopani wood, it will make your water soft and acidic. It will not increase the hardness.

Thanks for that, they fizzed so looking for something suitable....
