Dear UKAPS community,
I followed a DIY 4 dKH recipe here.
Unfortunately it ended up being 5 dKH according to my API test. Maths is not my strong suit, how may I adjust to make it 4 dKH? I opted for 1.2g baking soda and currently have 450mL of 50 dKH (after taking 50mL to make 5 dKH).
Edit: I also tested it using an Aquasonic carbonate hardness test kit, which turned yellow with 4 drops, indicating 40ppm according to the instructions.
Help much appreciated,
Thank you.
