i have bought a 40 gallon tank
2 feet high, 3 feet long & 15 inch wide.
first i put a ap2500 power filter but it was to fast for my tank so i replaced it with ap1500 power filter
i aslo bought a used gravel from pet store and also placed a used filter cotterage,
for about two days i cycled my aquarium then put about 20 fishes atonce and my fishes started to die continiously 4 to five each day( i put chiclids and other antigold fishes , when they die their colour turned into white ,and temperature of my aqua is 28 to 30. when my fishes started to die the second day i didnt knew what to do so as petstore keeper told me to put amoxill capsule powder 500 mg an antibiotic used for humans, in my tand and the next day change half the water as i was afraid to practice this i put 250 mg amoxil and next day changed the half water but it was not helpful at all,
i have a underground water storage tank i used that water to fill my aquarium and i didnt used any or the medicines or other anticlorine in my tank, test kits are not available in my country so i dont know what to do
as i am a bigginer i didnt kknew about nitrogen cycle
i read ur article about it and it was quiet helpfull thxx QUESTIONS
1 i am not sure if that is a disease or fishes dieying due to nitrogen cycle. is that a disease ???
2 do i need to continiously run my power filter as now i switch it off at a time when i go to sleep , and turn it on when i wake up?
3 if i assusme its due to nitrogen cycle , then how long should i need to cycle my aquarium ? at the moment there are 3 sweepers alive in it all fishes died,.
4 do i really need to use anticlorine?
5 do i need to change half water of my tank or completely change my water and wash gravel again ( i also washed my filter catterage and gravel when i bought it from store)
6 at the moment i dont have any heaterinstalled as temperature here in my city is warm about 35 degrees to 40.
