I have a 26 gallon tank which I keep
2 kissing garami
2 neon tetras(3 dead)
1 scissor tetra
1 red parrot (i dead)
Bio filter system
All thinks were good for for the last 3 months
i checked the water quality regulary and ammonia was low
as well as nitrate. the only concern I had during this time was the PH level
usually settled at 6.
all of a sudden I summer temps lowered causing a change in water temp.
it went from around the low 80s to 75-74 degrees. not really paying attention to this
I started to notice my red parrot fishes getting white spots. I treated the water with a
white spot medicine for the next % days as per the instructions which included water changes since filter had to be removed. After the treatment one of the parrots died and the other was not far from it. it looked as if it was having problem breathing. I noticed my other fishes were having trouble too. I seperated the remaining red parrot to a separate tank. after 3 days the red parrot was fine. During this time having done several water changes(25%) and adding water conditioners
I am running a Biological filter, which has worked great in the pass reducing ammonia to zero and keeping it there for long periods of time. For some reason its staying up for the last week. I do a daily 25% water change. I siphon the gravel and checked for decaying fish or plant. I have been feeding less.
How can I better control ammonia when it doesn't seem to want to be controlled? Also does lower water temp affect PH and Ammonia< and does a PH of 7 which I doe have because of the water changes affect ammonia levels
