I'm staring up a new tank for four weeks right now and I have reached the point where I want to add some Amano shrimps and Otocinclus. I have seen the first signs of brown algea, but that's probably related to the new setup.
I have created a pH profile during one day with a calibrated HANA pH pen and the profile looks like the list below.
I am afraid that the pH drop from 8.2 to 6.3 is too much for the Amano shrimps and fish (Rasbora). Every day a pH swing of almost two points. I don't want to use the animals as test material to see if it's OK to add them to the tank. What is your opinion?
I also dose 2.5ml EasyCarbo every day on a 53 liter tank and following EI-method. KH = 8.
10:40 - pH 8.2
12:20 pH 8.2
12:30 CO2 SWITCH ON
12:32 - pH 8.1
12:36 - pH 7.7
13:40 - pH 6.6
14:06 - pH 6.5
15:00 LIGHTS SWITCH ON
15:46 - pH 6.3
16:12 - pH 6.3
17:06 - pH 6.3
18:10 - pH 6.4
18:37 - pH 6.4
19:22 - pH 6.3/6.4 (display switching between those two values)
19:44 - pH 6.3/6.4 (display switching between those two values)
19:58 - pH 6.3/6.4 (display switching between those two values)
20:00 CO2 SWITCH OFF
20:10 - pH 6.4
20:30 - pH 6.5
20:44 - pH 6.6
20:52 - pH 6.6
