Thank you for the reply Fishlady. The small tank had been set up 2 weeks prior to putting the fish in but it was a new filter and at the time I wasn’t aware of cycling, I just knew I couldn’t put fish in a new tank straight away. This tank spiked at a reading of 8 for ammonia (nitrites and nitrates still reading 0) and I did a 50% water change. So I’m not sure if this has started cycling with the fish in.
Would it be beneficial to put some of the small tank filter media into the larger tank? The larger tank has gone to PH 7.2, ammonia 0, nitrite 0 and nitrate 5 although I had trouble distinguishing between the colours so it may be less than 5.
So from your reply I assume that I would be better putting the fish into the larger tank now. Is that correct?
I have recently “acquired” a 300 litre tank that had been previously set up for around a year. Due to the previous owners ill health I have taken it on. However after moving the tank to my home and rehousing the fish in a smaller tank, it has taken a week for me to set up the larger tank. The 3 filters were kept in bags and I haven’t cleaned them after reading that they can speed up the cycling.
1. Will the filters still be helpful for cycling the tank? Have they been out of water for too long?
On day 1 the reading were PH 6, ammonia 0.25, nitrite 0 and nitrate 0. I have added some API Quick Start to the tank upon recommendation but I am hesitant to put the fish in yet.
2. Has anyone used API Quick Start and is it safe for me to add fish now?
I am in no rush to add fish as I want to do it safely and not harm them. Just wanted some advice about the used filters as I have read that they can speed up the cycling.
