pH UP: Day #2

The Numbers

Date	GH	KH	pH	NO2	NO3	NH3/NH4	Temp °C
7-May	180	80	7.0	0	20	0.5	24°

Observations

• There continues to be a light foam wherever any object emerges from the water in the tank. This includes the growbed's intake hose, and tank perimeter. I thought it had dissipated, but it hasn't. However, it hasn't increased either.
• Last night, I noticed the plants were wilting. The temperature of the tank and the room was fine. This morning, they're fine. The chives seem to be doing better as well.
• The KH (carbonate hardness) spike from yesterday has returned to a normal level.
• Other than the KH change and the tank temperature readings increasing by one degree, other values are unchanged.

Analysis

I don't have any insights other than that I have to give the tank more time for the desired changes to occur. In the interests of getting the beneficial bacteria to start working on the ammonia, I am going to put in another round of pH UP solution. I will do this daily until I either get a pH of 7.5 or I start seeing a spike in nitrites. We'll see what happens tomorrow.
