On the 14th December, I noticed a white spot on one of my congos so after work went to the LFS and explained the situation and was given a product called ''White Spot Clear'' and to raise temp to 28C. Same night did a 40% water change and added 6mL to my ~180L tank (normal dose is 10mL per 100L).
Morning of 15th December found all my black corys covered in what appeared to be excess slime. And about 5 cardinal tetras missing. Same day after work went to the same LFS and explained the situation again and brought a water sample. Dude tested it out and no problems. Said ''White Spot Clear'' was probably reacting with something they can't test for so gave me tri sulfa tablets instead at a discount. Went home, found most of the slime on the corys cleared up and 3 more dead cardinals, 40% water change and added activated carbon to the filter. Let it run till the next morning.
On the morning of 16th December, removed activated carbon, 30% water change and dissolved 4 tri sulfa tablets in a bucket with aquarium water before adding to tank. 1 cardinal tetras went missing. No dramas. Also noticed that the ''White Spot Clear'' was expired in 2015.
Woke up 17th December and found one cory barbatus dead. Removed. In the afternoon found one emperor tetra dead. Removed. Later in the evening fish started dropping. Found 2 dead hillstream loaches, another dead barbatus (I think another one is about to die as well), one dead red whiptail and my apisto viejita red neck lying on his side with eyes really wide open. Not bulging but wide eyed. Tested my ammonia and came back at 0 with pH 7.6. Can't test for anything else. There may be some more fatalities but its hard to tell with all the wood and plants in tank.
Someone please help, what the hell's going on. I fly out on Monday, my brother knows how to feed and water change, not how to treat for sick fish. I don't want to come back with a wiped out tank. Please help. It will be greatly appreciated. Thank you for reading.
