pH fluctuations? GH drift?
1. what would equate to a very diluted 7.6 color? is that considered 7.6?
I would try re-doing the test. Make sure there are no bubbles in the drops when add them to your water sample. Also, make sure your test tube is clean, and don't cover the end of the tube with your finger. Use the cap. 2. can a pH drift from 7.0 to 7.6 in two days when you dont' do anything? Yes. It may mean the plants are stripping all the Co2 out of the water. How much light do you have over this tank? As for the GH...it could be a fluke in the water supply, or it could be something dissolving in your tank. Gravel, rocks, shells, etc. If you're using Onyx sand or gravel for a substrate, it will definitely raise your GH. Leigh http://www.fortunecity.com/lavender/halloween/881/ |
