Got a second hand fish tank today, - Blue lanet 160L l, built in filter, lights etc. It had had 2 parrot fish in it - the previous owner emptied it yesterday when she sold the fish. I took it home, filled it with water, put in the same gravel, same bio system, none of it cleaned (so I could kick start the nitrogen cycle).
added appropriate dose of Prime. An hour later, out of curiosity, I tested the water. Ammonia and nitrates zero, nitrates between 20-40.
I was expecting some ammonia perhaps, but not nitrates. Is it possible the bacteria are already well established and it won't need to do a full cycle? (Obviously get the nitrates down.before using it)
I've added fish food to kick start some ammonia any way. Haven't changed the water as it was new already,
wondering if I should keep using Prime daily, and do daily water changes to get nitrates down?
or wait and see if i get an ammonia spike?
have only just turned the heater on, and won't be putting any fish it in yet anyway!
