new co2 dissolving method & pH lowering!

I have 2 2L bottles with 1.5 cups sugar, and 3/4 teaspoon of yeast in a 50g for my co2 injection.

I got my co2 to dissolve well, and now it is making my pH lower extremely quickly! It was 7.2 prior to it, and now 7 hours later it is 6.6. I added some crushed coral to my Fluval to raise the KH, but I am hoping my pH will start to turn back around quick.

When should I expect to see the final affect of the KH increase to stability? Then I could assess whether to add more crushed coral or to take some out.

I have about 6 Tablespoons of crushed coral in there right now.

What is your kH? Drastic pH drops like this are a little scary... the kH should be at least 4 - 5 degrees to prevent that.

you probably saw my next thread, but the KH was 4.5 prior to a 40% water change, and is now 3.0, and I put on the new co2 specs right prior to the water change.
