    Well, i did initially test with vinegar and didn't see any bubbles. Note that the vinegar test tends be more noticeable if the rock surface is calcareous (coated in chalky calcium carbonate). Most rocks may not exhibit a bubbling effect... but yet they may still release some minerals, just at a slower rate.

    Weekly water changes can help to manage GH. The soak test can give you some idea of how much minerals certain rocks release over days and weeks. Over time, you'll figure out how much water changes need to be done to moderate any increases in GH.

    Do they still sell loose rock? Or is it in 25 kg bags?

    Mainly loose and by weight. But they also carry larva rocks in bags. If you are thinking of buying more the bag is cheaper compared to the normal per kg price.

    I bought some grey ones with white lines from them before but discarded after using for a while. Found they had the "powdery" feel after using for a while, did a vinegar test and ended up they were very reactive. That's why I discarded them! A waste but the white lines were beautiful and contrast with the grey.

    Re: Rock Distributor @ 40 Jalan Lekar

    Today I just went there to buy some rocks. Those grey rocks left quit little, and most of them in plate shape which dun really look good for ascaping. As for black lava rocks, also limited stock. Worse, the hammer was broken thus they got no hammer to lend me. End up I have to use rock to crack rock. Heard from the staff their boss got intendtion NOT to restock the rocks any more. Thus left so little for you to chose. So if you still going, go at own risk.
