just tested my water for hardness and my salifert tests tested about .26 which is KH of 11.8 and alk of 4.23 NSW is 8 KH of 8 and alk of 2.9 how can i get my water correct, i have kents superbuffer and no i am not using it, should i start using it? it says it will get your ph to about 8.3 and keep it stable my PH tests about 7.8-8.0 with salifert test kit as well. any knowledge is appreciated

That sentence was slightly confusing. Was the dKH 11.8 or 8.0? I try to keep my alkalinity around 12dKH, which in my opinion, is great for coralline growth. 8dKH, in my opinion, is on the low side.
The pH could be raised using a high quality pH buffer, until you get it around 8.2

mine is 11.8 and a alk of 4.23 is that ok? NSW is 8 with a alk of 2.9 so that is why i was worried. will the kents superbuffer work for my PH? or will it wack out my alk as well?

i found this about the superbuffer see what you think :
Kent Superbuffer-dKH is a specially formulated pH buffer and alkalinity or carbonate hardness (KH) builder, designed to adjust the pH of saltwater aquariums to the range of 8.0 to 8.3 and build the KH. Superbuffer-dKH is the finest buffer available for either fish only or reef type marine aquariums and is designed to mix clear with little or no cloudiness or precipitation. Will not flake on your corals as other competing products can! Compatible with and designed for use with Kalkwasser Mix, Concentrated Liquid Calcium, or Turbo-Calcium by Kent Marine.

How old is this tank? what else are adding to it? I would look at something like B-ionic or C balance.

test your calcium as well.......pH, alk and calcium all have to dance together to be at proper levels....when all three are balanced, you wont have to worry about your levels!
p.s. i think that your alk is fine where its at.....especially if you are keeping sps!
good luck
