Ya, 0 nitrate. The last time I had a tank issue related due to holes on head disease was about 6 months ago and I had to do a 90% water change to recover from it.Donthemon said:O nitrates?
Don't add baking soda. Get some crushed coral and add it to your substrate-about 1 pound of crushed coral for every 10 gallons of water. It will slowly raise your pH and help stabilize it. Baking soda changes your pH too fast and is only a temporary fix. You will kill your fish screwing around with your pH that way if you don't know exactly how much to use and how often to add it to the water.gordonhtfu said:I am planning to add some baking soda to increase the pH
To answer the first question, no it is not normal for them to lay on the bottom.gordonhtfu said:I confirmed that nitrate is 0. I shake the bottle and mixed solution for a minute each.
I also found that pH is at 6.0 or less. Ammonia at 0.5 and nitrite is at 0.5

Thanks for suggestion. The heater is working fine. It is at 80FJoe L. said:Have you checked to see if your heater is working properly? Being that they are warm water fish, if the water is too cold, they can possibly become very inactive and lazy and kinda shut down a bit.
I got some crushed coral. How much should I add for 6.0pH for a 120Gallon Tank?DanInJakarta said:In answer to your question: no, it is not normal for them to sit on the bottom, unless they are sleeping.

pH affects nitrification. From Researchgate, "Nitrification becomes inhibited at a pH below 6.5 and stops at a pH of 6.0."
You're original post claimed a pH of 7, now 6.0 or less. Any increase in dissolved CO2 in the water should lower the pH. The outgassing of CO2, causes pH to rise. So, if one lets a liter of water to stand overnight and measure the pH, it should rise.
If you went from a pH of 7 to 6 in a very short period of time, I would suspect pH shock for the fish. A difference of 1 in pH is a 1000x difference in acidity.
As the pH of your water seemed to change quickly, I suspect the calcium hardness (KH-alkilinity) is low.
Bicarbonate is fine, but there are consequences to using it because is sodium bicarbonate, not calcium carbonate, and the danger of pH shock by applying too much. A .2 change per day is a recommended maximum. Another alternative is to add more aeration to newly changed water. This will increase out-gassing of dissolved CO2 as well as having plants. The out-gassing occurs over the first 48 hours, so if this were the problem, then you should see a natural rise in pH.
Crushed coral is a good stabilizer because it a calcium carbonate so it will not only raise pH but also increase calcium hardness so that the water can resist pH changes.
12 pounds rinse it well then scoop.it in tank.gordonhtfu said:Thanks for suggestion. The heater is working fine. It is at 80F
