Hi all from down under!New to the hobby, started with new 140ltr freshwater tank with the aim to house gouramis. Got anubias and two other low light plants I can not name, put 6 zebra danios to cycle. In two weeks testing of water seen no nitrite but gradual build up of ammonia and no nitrate (testing with API). Thinking it needs more ammonia put 4 more fish from the old 38ltr tank plus added bacteria from almost expired dated bottle of Cycle something rather.
When ammonia spiked in a few days to 8 and still no nitrite, panicked and put ammo lock, then when same reading for two days in ammonia (did not know that API shows both ammonia and ammonium which is what ammo lock does to ammonia) have removed all but one fish. Cloudy/milky water for a week, danios back in there, ammonia/ium still at 8. Doing partial water changes of 10-25% twice a week. Two weeks on no changes
Do I have to start with fresh water because I have used ammo lock that does still convert all ammonia and prevents cycling the tank???
Thanks for the advice!
