API Buffer Max. My tap water is about a 1-2 kH. The directions do not give an amount to add to the tank to increase kH but i add only 1 scoop at a time/day then test (it comes with a scoop in the bottle). It usually takes me about only 2 scoops to get my kH up to 5 and i have a 65 gal tank.

SO IT does really matter then about GH? My KH is 4 and my GH is 8 or 9. Plants are growing well, but I always think there is room for improvement.

Do I need to lower my GH? Is there ANYWAY to do this other than RO and then adding booster?

Adding a bit of crushed coral to your filter media will up both KH and GH as long as your pH in the tank is below 7.0. I have had KH-related pH crashes, but this was with a KH of 0. Added the crushed coral and voila! No more pH irregularities. I am sure that the KH was not the only possible cause, but the crushed coral did fix the problem. My tap water comes out with 0 KH and a GH of about 24 degrees. Never had any trouble due to GH though- at least that I know of. I do not frequently test the GH or KH these days though, because I have found that for the species of plants/fish/inverts I keep seem to really not care too much about TDS, GH or KH, except for possibly how they relate to the pH.

I even have duckweed in my water bong!

this is overall good parameter, no need to change anything.

KH is important if you have fish.
That measures the minerals that they need in the water.
Crushed Coral is a better option than Baking Soda.

Discusluv,
I am not mocking anybody. Greggzís and madcraftedís posts above are hilariously funny and my comment about using the Search button is a compliment to Bryan Hearn for finding and continuing this thread instead of creating another one.

I had been a moderator on APC forum for several years and our moderating team preference was to encourage members to use the search function in order to learn from and continue posting in the existing threads.

Edward,
When you were a moderator did you welcome as well as offer guidance?
The new member hasn't been back- maybe direct your explanation toward this person.
I dont need one.

Greetings, I'm browsing through the postings cause I'm a newbee and the hardness question is first on my list of many more questions for you experienced fish keepers. I'm not sure I understand the readings from the API GH&KH test kit. There is no color chart to compare color values and I could use some educating.

It took 8 drops of the GH solution before I noticed a color change. Does that mean I have a 143.2 GH hardness ? It took 3 drops of the KH solution until I noticed a color change. Does that mean I have a KH hardness of 53.7 ?
