PH to KH problem

**Kevino** · 29th Jul 2005, 21:58

Kind of long story.

3 to 4 weeks ago, I've tested my tank with a portable PH meter and drop check it reads between 6.9 to 7.

1 week ago I've introduced log tied with Java moss.

And just 3 days ago bought a PH monitroing meter from a bro here. Once I've calibrated and setup the meter my PH read 5.5. Double check with my drop check with approximate the result.

I was shock and seek advise from one of the bro here is to change water. I've changes 50% of the water and the PH when up 5.8.

Next day consult Mr Chan from NA and he recommended me to add in KH up to bring up both KH and PH up.

He advise to dissolve 2 teaspoons every for 3 days then see if the PH goes up. Indeed it when up to 6.8 on the third day which is today.

But now I've checked KH with a drop check and it reads 8dkh.

What happen? And will high KH harm my fuana and flora? Please advise.

Regards,
Kevin Lee

8dkh isn't considered high, I believe some of the members have hit above the 10 region mark without any effects. you should refer to the kH/pH chart to see the correct perimeters. Once you increase yr kH, you should use co2 to achieve the correct pH
