Hi guys,

just a quick question: is it ok to use bottled mineral water,
when changing water in tropical aquarium? Thanks in advance!

The bottlers are under no obligation to keep the same recipe. In fact
they probably use more than one bottling facility, so your bottle's water
parameters may vary by batches. For fish, stability in water parameters
is good, so if using bottled water, use small water changes often if you
are not certain of the water's parameters. ymmv
