How to reduce alkalinity levels

[kyabk]

I was just testing my Calcium and Alk levels and noticed that my Alkalinity is high according to my tester. The indication on my tester is low, normal, and high so I don't have a number to give. The tester that I have gives instructions on how to increase the Alk but no instructions on how to reduce if to high. So with that said I have to questions:

1. Is having a high alk bad? Can it hurt the fish and other living things in the tank?

2. How can I reduce high Alkalinity?

Thanks in advance.

What alkalinity test kit are you using? I recommend you get a salifert alk kit, they run about 11.00 and are much more accurate since they test by measuring the titration in ml. Second what do you consider a high alk? I consider anything over 14dkh high. You alkalinity will come down as you add calcium chloride and then will stabalize where they are in a balance(Calcium and alk). Hope this helps you out

Also what is your ph? if it is high and so is your alk then I am guessing your calcium is low, like in the 320-350 range. read this http://www.reefkeeping.com/issues/2002- ... /index.htm

you could do a small water change. make sure the temp and salinity are the same. you need to get a salifert test kit. ph should be 8- 8.2 your ok. how does your corralline growth look like?
