Dropping PH
Here are more details to answer your questions: - KH no reading means that when I put the first drop of reagent the water color turns from 100% transparent to slightly yellow. As I add more drops the yellow increases. This means that I never have a color change from blue to yellow but I always see yellow. We can probably say that KH reading is zero. - The other 2 10G tanks do not have any additives to control PH, such as crushed coral or others. These tanks don’t have any plants or gravel, but only few decorations to keep them clean - The 46G tank is heavily planted without any driftwood. The substrate is very fine gravel (not sand). When I clean the gravel I never stick the siphon into the gravel to avoid uprooting the plants. Actions taken so far: - Ordered a new GH/KH test kit online. I should get it by Dec. 18 - Added 2 TSP of crushed coral to the 46G. That apparently brought the PH to 6.4. - Bought and used a UV sterilizer for 2 days in the 46G. Amazing to see that in only 1 day the water turned completely crystal clear from being sightly cloudy (i.e. a little whitish, not green) I will post new results once I get the GH test. In the meantime I’ll answer any other question. I live in Belmont (CA) in case anybody is experiencing the same problem in my area.
