CRS kh and GH?

jlui83 · May 20, 2008

What is the KH and GH supposed to be for successful CRS breeding?

My KH is 3
and GH is around 7
Ph is around the 7.5-7.6 range
It WAS around the 7.0 range until I added the sponge filter.
I'm going to do a water change today and see if that has an effect to it

Other studies

Tap Water- KH 2, GH 6, PH 7.0
48hr Aged Tap Water- KH 2, GH 4-5, PH 6.8-7.0
Brita Water Filter- KH < = 1. GH 4, PH < = 6.0
My tank water- KH 3, GH 9, PH 7.5-7.6

I just bought a GH/KH tester thats why I decided to test now. Its quite difficult to REALLY determine when the color changes, Do you stop adding drops when you see the first sign of color change? or when the color is SOLID?

Oh its the API testers
Thanks!

Tank water after water change:

PH 7.4
KH 3
GH 6-7 (after the 6th/7th drop the water started to turn color)

Ideal PH for CRS is around 6.5 for best color and breeding....

Cheers, Bill

New update on my Parameters.

PH: 6.8-7.0
KH: 2
GH: 5-6

I'm trying to figure this out too. I brought my tanks ph to a little over 6.5, and now I am trying to figure out the GH and KH.

Afyounie-
you should be ok. if your ph is that low, your gh/kh should be low as well.

Cool, I really like the look of CRS, and I really want them to be happy and breed.

Just get some ADA AS, put it in a cooler with water for a month or two, changing the water every few days and stirring the AS.

Then you wont have anyting to worry about but feeding them and doing water changes.
