Sherwin, you getting in-coherent... I don't how to how my tank water. []

I use Baking Soda in my tanks, maintain at around 4.

Sorr vinz,
Thanks for pointing out my typo..... juz back from Jakarta. They put me on waiting list for 5 hours.

I think you got what i mean.. I wanted to know how you guys maitain the water hardness. For me I had to add Baking Soda during every water change.

Was given some KH up fr NA 3 week ago. Think it is selling at $5 per container. Don't know if it is some form of baking soda. It is in white power form.



Hougang area
PH - 7
KH - 0
floor: 11/20

[vinz]

Yes, it's baking soda.

Just got a bottle of 'Bicarbonate of Soda' from Ang Mo Kio NTUC.
Brand : Bake King
Cost : SG$1.00
Weight : 100 gram
Description : Red capped white bottle

By the way, using the test kit, do you guys measure the KH values from the first drop of the solution that turns the water blue or only starts on the second drop?

[sherchoo]

According to instructions, it should be the amount of drops.

Pasir Ris 8/12
pH 7.0-7.2
kH 1-2

btw do u add the soda bicarbonate straight into water or dissolving then add? ... my kH in the tank is only at 2 now ... what is the optimum kH?

[Goondoo]

wow...
in that case,

stats of my 16" tank
PH 8
KH 7 (dunno how it got that high...)


From Tap and also the 4' tank,
PH 8
KH 1
Area: Ang Mo Kio
Floor: 8 of 12

Would there be a difference to add in day time (CO2 on) and night time (CO2 off)? My PH varies about 0.3-0.4 in between.

Hi Joe,
According to the link, dissolve before adding to the surface of the water.

[joe]

thanks goondoo ... kh=4 is what i should be striving for?

[vinz]

Joe,

Depends on the pH and CO2 level you're aiming for.
