My community tank (neons, peppered corys and dwarf gouramis)
has a ph of 7.6, and I'd like to lower it for the fish.
The rainwater I usually use to change the water is usually
at 6.5 and this works but recently its gone down to 6.0.
Will it harm my fish if I put it in there?

Hmm, rainwater? I've never heard of using rainwater
for a water change. Have you ever tested it, because I would
think it would have alot of pollutants and things in it.
And I don't think it would be good for the fish to lower
the ph by adding water with a ph so much lower, it has to
be gradual. I've seen chemicals that lower ph, but I
really don't like adding unneccesary chemicals to the
tank. You want to lower it gradually, but I've never
really had to do this, so hopefully someone else can help.

singin in the rain..oh singin...okay so if rainwater is
from an unpolluted source resulting in acid rain it should
have a ph level of 5.5 to about 6..so your is about right...what
happens is the rain absorbes C02 from the air and dissolves
with the H20 starting a reaction that produces carbonic
acid just like adding C02 to your tank dropping that ph...if
you let it sit around for a bit it will probably go up...also
depending on the time of year that could all change too..now
as far as adding it to your tank...just add it slow and
things should be fine..

I've always used rainwater, never had any problems...I
added it and it was fine. I was just a little worried bc
its usually 6.5 and today it was 6.0! Oh well, everything
turned out well.
