Water Change After Fishless Cycle

[rust81]

I am coming to the end of my fishless cycle on my 130L tank and today performed a 90% water change for 2 reasons - 1) to move the tank to a new location and 2) to raise the pH. I think that i probably have a few more days before the tank is cycled as nitrite is clearing to 0 but not quite in 12 hrs yet.

When my cycle has finished - will it be ok to put my zebra danios in from my Q tank, or do i need to do another water change? I have been using household ammonia from Boots to do the fishless cycle and this is all i have been adding to the water (apart from dechlorinator)?

I had to do a premature water change myself to raise the KH and PH.. both had crashed and subsequently halted the cycle. In fact even some amonia remained after 24 hours. Hang in there, you sound pretty close now.

You will probably need to do another large water change and get the tank up to temperature, but this is mainly dependant on the level of nitrates in your tank. Mine were sky high and needed the water change. Im not sure if there is any other reason to do the water change, as long as the ammonia solution has nothing else in it. Perhaps it's best to do it just to be on the safe side. Pain the in the butt, but saves any risks.

That is the main question i have - if i can get away without doing the water change then i think i would prefer to do that. The ammonia solution should only have ammonia in it and the 90% water change i have done today has dropped the nitrates right back down. Anyone else think a water change is needed before the danios go in?
