water changes

[jaypython]

Hi......is it true that when you carry out a water change and use tap
water instead of R.O or deioinized water,the ph always settles at around
8.0-8.4......and is this ph ideal for most marine fish??

Also....do you have to mix the new water going in-into a bucket and keep
it warmed and oxygenated overnite(24hrs) before putting in the
tank....is this really neccessary??

any help.....much appriciated.

pH is determined by the oxygen level in the water and the
lack of CO2 in your home. It can settle to a normal range
in most cases. If you premix it and let it cure for 24
hours, it tends to match the tank's pH quite well. Try to
mix it in the same room or vicinity as the tank, as that
tends to be the same pH-wise.

I don't recommend using Tap water at all. I did it for
years, and had lots of algae problems and super high
alkalinity. RO/DI water is far more reliable.

pH measure of the concentration of hydrogen (or hydronium ion) relative to
hydroxide ions in water. It is not a measure of the oxygen level in the water.

The CO2 dissolving does have a baring on lowering the pH. It drops the pH of
DI water from the theoretical 7.0 down to about 6.2 or so in normal
atmospheric conditions.

Okay. :) I'm not a scientist, and pretty much hate chemistry.

That is true. However, that wasn't the issue. The issue was what pH actually
measures. It doesn't measure the CO2 content or the O2 content. It measures
the concentration of hydrogen (or hydronium ion) relative to hydroxide ions in
water.

thanx for the info guys...

i always tought ph was a determination of how acidic or alkali water
is..but didnt realise that curing it overnite would help such matters...

cheers

jay;)

I suspect it depends more on your water, and varies from location to
location. I do know people who have pH problems with well water.

You guys have me dreaming about this at night practically, i have thought of
pumping in sea water regularly since this original post, lol.

solar powered siphon pump, and valve flow controlled tank siphon with auto
emergency shutoffs. Dont want to flood the whole neighborhood with
seawater!

could be timer controlled to change tank twice daily simulating tides, and
set for a slow change that lasts about an hour, which will further create
currents. only problem, now this hobby is requiring not just to move tank
location, but the whole dang house! lol
