After the 20% wc, Amm 0, trite 0, trate 5, Ca 400, Alk 9, Mg 1300, ph (as measure by a pinpoint probe) 7.8 (night) - 8.2(day). This is generally where my parameters stay. [All test API except Mg - Elos. Results confirmed by LFS using Elos test kits]
Up until last week, I have been using kalk to maintain Ca + Alk between w/c. I would manually add 10mL of kalk solution (1 tbl spoon per 1/2 gallon) at night into the rear chambers (Tank is a 29g Biocube). This was not maintaining the Ca or Alk levels so I decided to try 2-part -- Brightwells. I tested and added 10mL of Part A, then 5mL of Part B. pH has been 7.7 - 7.95 since. I can't figure out why. Have done a 20% wc yesterday and no effect on pH range.
I have read Randy's articles and thought CO2 levels might be an issue (but they werent the rest of the winter?) so I opened all my windows and opened both access hatches. I even tried bubbling the water.
Any ideas? Pointers? I'm not trying to chase pH but 7.7 is out of acceptable range isn't it?
