KH and Safe-T-Sorb
I just did my 40B with 40lbs of Safe-T-Sorb, normally my kh is around 3 and my GH is a little higher 4 or 5. I mix tap water with RO water to get it like this. Out of the tap KH is I think 19 and GH 21, I'm not really sure haven't tested it for a couple months.
Before with flourite my kh/GH would never change. Now my GH still remains constant but my KH is bottoming out to 0. I added 1, 1/4 tsp baking soda to get the KH up to 2-3 yesterday. Tested and it was at 3. I tested it today after I got home and it was at 0 again.
I added more baking soda, my question is, will this fluctuation in KH hurt my fish?
How long will this go on for?
Should I add more baking soda then 2-3 degrees worth?
