The pH will fall on its own over a few hours to a day. The alkalinity will fall on its own over a few days.
Is the water cloudy?

Thanks for the replies.
It does't seem to be falling much, and its been around 18 hours since I overdosed it. The water isn't cloudy, and there doesn't seem to be any adverse affect on any livestock - yet... I read an article which suggested adding Baking Soda (??) or White Vinegar (??). Are any of these worth considering? Thanks Quote:

You don't need to add anything. The levels will fall on their own, just give it time. If the water is not cloudy, you'll be fine in a week or so.

Definitely not baking soda. That raises alkalinity. You could dose a little vinegar or soda water to drop the pH if it is still high, but that is unusual to still be up above 8.5 the next day (unless you are still dosing), and might even be a measurement error. This article has more: High pH: Causes and Cures http://reefkeeping.com/issues/2005-03/rhf/index.htm

Thanks for the help.
One article I read said that Baking Soda would try to get PH to 8.2 If its above, then Baking Soda would reduce the PH, and if below, it would raise it... Is this nonsense? My system is 1100 litres, so I guess I'd need quite a bit of Soda water to reduce it this way? Thanks Quote:

Soda water is not the same as baking soda. Baking soda I believe is CaCO3, and will raise alkalinity. Soda water contains CO2 gas, which forms Carbonic acid (H2CO3) in water, which lowers pH.

Baking soda NaHCO3, sodium bicarbonate. I got confused with Aragonite, CaCO3. Sorry for the confusion.

If its above, then Baking Soda would reduce the PH, and if below, it would raise it... Is this nonsense? Mostly. Adding buffers and baking soda to raise or lower pH mostly just ends with elevated alkalinity. Your alkalinity is already too high, so it is not a good option.
