    From my own experience, all rocks will change the water parameters over time... the difference is how fast and how much it changes. The quantity/mass of rocks used vs the water volume, the buffering efficiency of the active substrate, along with frequency of water changes also affects the rate of parameter change too.

    I have tanks with lava rocks which gradually increase in pH too, but the changes happen slowly over the course of a few months, so the livestock are okay. What matters is the parameter changes are gradual, as most fishes and shrimps can adapt to those changes over time.

    Though if you keep super sensitive fishes or expensive shrimps which cannot tolerate even the slightest changes in water parameters, then you'll just have to avoid rocks altogether. Case in point, most high-end CRS shrimp breeder tanks are almost devoid of any rocks or hardscape which may affect the water chemistry, as they just can't take that risk with such expensive livestock.

    The only rocks which don't affect parameters are those fake plastic/resin rocks, those are confirmed 100% inert.

    So if there are bubbles, mean not suitable for tank scape?

    By by the way note they are closed on Sundays. Went last Sunday and didn't get to see anything!

    I guess as UA mentioned, all rocks will affect the chemistry of the water to some extent as majority of them are not inert.

    However, some rocks are more reactive and would cause the chemistry of the water to change faster than others. Such rocks would cause water chemistry to change rapidly so they would not be as safe for livestock.

    So in that sense, yes, if there are bubbles that appear when we pour vinegar on rocks, that would mean that the rocks are far more reactive and are less safe for livestock and should not be used.
    Cheers,

    not really true, almost any (beside radio active ) rocks can be use, just need to choose the right live stock, that is all.

    I would trust bro Shadow's advice on this rather than my own
    A lot more knowledge and experience.

    Although I would still like to think that the less reactive rocks would give you more choices on fauna

    Re: Rock Distributor @ 40 Jalan Lekar

    Hi, I bought some rocks from NA (Thomson LFS) recently. When first placed in cycling tank, it was grayish white. Now after 1.5 weeks, it has changed to grayish yellow/light brown with slight whites.

    Is it normal for rocks to change colour this fast? Or should I remove and do the vinegar test? It is only a planted tank cycling now so I am uncertain if I'm "poisoning" the water.

    I assumed buying from a LFS would mean its safe to place in tank items. I did scrub the rocks prior to introducing to the aquarium.

    Eh... algae? Diatoms? Rocks do change colour slightly... but of course no dramatic changes ...

    Most likely its just algae or diatoms growing on the rocks, they usually create a sort of yellowish/brownish tint to the lighter colored parts of the rock.

    You can try using a brush to scrub those areas, see if the algae can be cleaned off. Alternatively, once the tank is cycled you can introduce algae eaters like otocinclus or shrimps and they will help you clean it.

    Only way to know if the rocks are affecting parameters in your particular tank setup is to test the water regularly and track it over time.

    Ohh diatoms.. possible. I'll go home and examine the rocks again!

    That's sounds like a brilliant idea! Food for my future livestock hehe.. I'll check and see if I am able to clean off the "stains" if yes, ill leave them be till tank is cycled thanks guys for replying!

    I did not go there, just hijack this tread to ask whether are this lava rocks. I got a box of these from a landscaping company.

    Re: Rock Distributor @ 40 Jalan Lekar

    It's definitely not lava rocks but I m not sure what they are either. Did you pick it off from somewhere or was it bought as it seems like there is quite a bit of dirt/dust on it
