need some clarification on my water chemistry

Ph is 6.9(+/-.1)

Kh is 7

gh is 13/14

temp is at 77.5

Can anyone clarify the relationship between gh and any of these things. I understand the kh/ph relationship in regards to Co2 but does my temp have a factor in this. Furthermore does gh play a role in how well the water absorbs Co2?

I hope I can get some help because by default my tap water is 7.6 ph and the lowest I can get it with DIY(yeast/suger/water) is 6.9(+/-.1). I have recently made a beast of a reactor to try and push it down further, but maybe I dont need too.

Furthermore, I have figured out how to run my emperor filtration on medium without any surface agitation. So there is currently nothing creating surface agitation.

Thank you

There is really no relationship between gH and any of the other parameters you listed. gH is gH.

Temperature has a small effect on the pH/kH/CO2 chart but it is generally ignored in the hobby because it's a small effect.

How much lower you do want the pH to go and why? You are pretty close to optimal CO2 readings now.

This really should have been posted in the Water Chemistry forum. Read this document and pay attention to #4.

thanks for your help rexx. And furthermore, General planted tank discussion. without the word general in there may have lead me to the chemisty forum. But then again there is a forum that already says plants on it as well. So people who talk about plants on "This" General discussion forum should also be removed to the plants forum.

According to the dictionary the word general meens- not confined by specialization or limitation. So the word General next to the planted tank discussion would meen no limitations on what you talk about in the paramerets of a planted tank.

Your advice is great, your ability to read the headings on the forum is wrong.
I know where I should be posting a question. And in this forum there is 2 places to post for every topic. Its specific destination, such as plants, shrimps,chemistry ect...... And the General planted tank discusion.

Thank you,
Ry
