Ok.. so I did a fishless cycle.. I dumbed 12ppm of ammonia in everyday for a month till it was completely cycled and there wher eno nitrItes and ammonia was gone bye the next day.. then i added fish and stopped adding ammonia.. the ammonia then started to climb.. so atfer three days of prime treatment.. I seeded it with goldfish filter media.. this stopped ammonia for two days.. then today i notice my cories barbels are TINY! and I test ammonia.. liek i do everyday and it is 0.50!!
What the devil is going on?!!!!

What the devil is going on?!!!!

but my question is.. how can it be fine for 2 days then stop? I mean those goldfish tank media noddles are bact filled.
ugh.. that canister filter is cursed I say... the ammonia is now definatly (three tests one with a different kit) zero. this is the same thing it did on my goldfish tank.. ugh..
