Please can someone please help me with a known good 4kh solution and easy to follow.
I screwed up big time last night. I made a DIY Drop Checker I don't think the tube I used allowed for
good gas exchange. The new one I made will work better being the design it is allowing for greater gass exchange. All the pics are on my phone and I have a chance to use a pc right now so I will post pics later.
I have for test kits to work with are API pH Test Kit "Blue" and Tetra Easy strips for 6 test on one strip.
The reading of Kh is on 0 40 80 120 180 300
So that chart that out there is not helping me or I'm not just understanding this.
Please help. I just made a sad and expensive mistake.
