This is linked to a question I asked earlier in a different thread.
I use RO water in my tank, and I currently remineralise using JBL Aquadur.
I have done tests, and found that adding enough Aquadur to raise the TDS to 100, brings the KH up to 0.75.
Based on this, if I want a KH of 3.75, that means a TDS of 500!
The water I made up which was of 100 TDS and 0.75, I tested the GH of that water too. The GH was reading 5! I think my test kit must be wrong, because JBL state that an increase in 1 KH using Aquadur equates to an increase in 1.6 GH. Clearly my GH test must be incorrect, so let's forget about GH for the moment.
I know for a fact my KH test is correct, and I am concerned because using Aquadur means that if I want a KH of 4, that means a TDS of over 500.
So, shall I add Sodium Bicarbonate to my pot of JBL Aquadur? This will mean that I need to add less TDS to reach the same KH?
I hope I have explained all this clearly. Any advice is much appreciated. Cheers
