This is just a guess but I would say 3 bubbles per minute. I am going to set up a bubble counter tonight. The CO2
indicator is dark green which according to the color chart means the right amount of CO2
. I have the line attached to a diverter valve that allows me to slow down the flow. I usually shut it off at night and the PH rises back up to 7.2. During the day, with the flow continuous, that is when the PH will get so low. I can tell when it is because my fish start acting erratic and falling on their sides. I have just been adding baking soda and getting it back up. The fish are fine then. It doesn't do it every day but I am away a lot and I am afraid it will do it one day when I am gone and the fish will die. All the loaches but one died. The one left looks fine. Its' color is good and it is active when the lights where off. The ones that died had red gills that looked like blood veins showing through and tjey were staying at the top of the water.
I am not too worried about the CO2
right now. I will keep working until that is lined out. I really would like to figure out why the loaches died. I would like to get more but not until I get a better QT filter and figure out why the others died.
I wonder if them being bottom feeders, they died from cyno bacteria poisoning or maybe low PH? My nitrates jumped to 80 too for a few hours. It was fine in the morning then, later in the day, the fish started acting funny. I tested the water again and the nitrate had jumped way up. It went from 20 to 80 in a few hours with no rise in ammonia or nitrite. I didn't know that was possible. My test solutions are all new. Except for the PH one. I have been replacing the individual tests as they run out. I test a lot because I am paranoid.
