checked my parameters and every thing look grate but the PH was at 8.0 and the KH was at dkh7 ppm125.3  my test kit says the kh should be at between 8 and 12 dkh and ppm at 143.2 to 214.8 so what dues it do to your corals having it that low? what will bring it up? klasser? is there anythng from the kitchen that will work? Thanks Glen
Here some great reading http://reefkeeping.com/issues/subject/chemistry.php if my ph is 7.8 --- 8 5Â I consider it fine, it changes through out the day too with the lights & air
Ph of 8 is just fine especially in the winter when the house is mostly closed up. As for alk there are numerous additives for it or go to the chem forum here and read the Randy Holmes Farley article on making your home mix. Baking soda is the item you want to use. Raise it over a period of days not all at once. 7 isn't enough to get stressed over and it only even matters if you have corals with skeletons, if all you have is softies and no clams don't worry about it.
thanks guys I added a little backing soda and it is up to 9 on the KH and it also set my ph at 8.2 some thing I have never been able to get in that tank. I rembered reading the artical when john posted it but I had forgoten where it was. Glen
I wouldn't raise it over about .50 a day, otherwards it should take about 4 days to get from 7dkh to 9 dkh. slow is the best. To late now.
thanks John I was shoting for 10 and when I seen it had jumped to 9 I stoped for now I thought that was going slow lol, I guess slow in a reef tank is a week. Thanks Glen
