Have you actually tested your taps ph? In order to get a correct reading you need to put some tap water in a cup and either aerate it or stir it occasionally over 24 hours to let the water gass off then test the ph. This will give you the true ph of your tap water.
Yes i think i tested my waters true Ph not to long ago, it was 7.0 right out of the fridge and still read 7.0-6.8 after the 24 while being aerated.
I read that its normal for the growing bacteria to use up the kH
, and the buffers while being produced, and usually causes the water's pH to drop, rapidly. So i found out that people with this issue manually dosed the pH back to 7.5-8.0 using Baking soda. During the final days of cycling, they slowly let the ph drop to its "normal" state so the bacteria doesn't die off. I guess my tanks normal water state is around 6.5 pH, without any buffers.
Rivercats, where can I buy crushed coral? I looked up Petsmart and Petco, and neither of those two seem to sell the crushed corals... any specific types that i should buy? Please let me know, I want to add the the bag of coral to the tank so i wouldnt have to add baking soda every day.
