In an earlier post I reported these test results
Calcium concentrated in ppm: 415
KH value in dKH: 7.7
Alkalinity in meq/L: 2.74
I was told that I should add buffer to raise the dKH to 8-12 (my goal is 10). I have search for an hour now and I cant find a clear way to do this. Can someone give me a step by step proceedure?

I doubt if you need all the info below but I already had it typed out so I figured what the heck!!!


Heres where I am now:
  • 1. I've been doing water changes battling a spike after the new tank was moved to the house about 6 weeks ago.
    2. I figure I still have a little work to do before the levels are solid at 0 (currently: trace of ammonia, 5-10 Nitrate, 0 Nitrite, 8.2-8.3 PH)
    3. I don't run rodi water, I have plans to add a system nest week
    4. The temp issue seems to be solved... solid 80° with very little flux day/night
