Hi Everyone,
First time post here , bear with me 😀👍
I have a conundrum,
My tank for crs has the following parameters:
Ph6.7
Gh 6
Kh0
Nitrate 0
Tds 146
Using shrimpking active soil
Salty shrimp gh+
I need to do a 10-20% water change ,
Yet I cannot get new water quite right.
Using a hm calibrated tds meter I get the gh to 6
And yet the tds is only showing around 86-90.
RO source is 0 tds.
Do I need to match the TDS in the bucket to the old tank water? If so then by adding more salty shrimp Gh+ To the new water , the tds will rise to a good 130-135 yet the gh then increases to 7 gh?
Would that be to hard/high for crs?
What should I aim for with the new water? a lower closer matching gh of 6 (TDS86-90) or a higher Tds of 130-135
(Gh7)?, or is that to high?
My original wat tds in the tank doesn’t hardly move from one week to another tds 145
Which is more important ? Tds of 140 (gh7) or the Correct gh6 yet lower tds?
Sorry to confuse, or am I just over thinking things and just get the gh to say 6 or even 5? And ignore the tds reading ?
Thanks
Andrew
