New 29G with filter question
Hi there. Last weekend I set up a new 29 gallon tank to which I moved a fully cycled Seachem Tidal 55 HOB filter; it has been a secondary filter on my 75G since March. It thought that because I was using this filter, which has only ever been cleaned in used aquarium water, that my tank would basically be cycled, cycled enough for a couple of fish to start things out anyway. However, it apparently is not since I am getting readings for NH3, NO2, as well as nitrate. Here are the readings as of yesterday:
NH3: 0.5 NO2: 0.5 Nitrate: 20ppm pH: 8.0 KH: 10 GH: 4
29 gallon glass Aqueon tank
BDBS substrate with Osmocote tabs added here and there (probably 8 - 10 I can't quite remember)
Seachem Tidal 55 filter (cycled)
Sponge filter (previously unused)
2 small pieces of Manzanita wood
Several river rocks/pebbles and 1 piece black lava rock
Plants, of course just planted so not doing too much yet: Bacopa, 2 x Swords, Rotala, Crypt. spiralis, Broad Leaved Chain Swords, Mayaca, Hygro corymbosa, etc. Plenty of plant melting going on.
5 x MTS from my 75G 2 nights ago
There are two possibilites for the ammonia and NO2 readings that I can think of.
1. Monday morning when I was leaving for work I checked the tank and the filter looked like it was about to overflow. Since I was in a hurry, I just unplugged it and left for work for the day. Could the bacteria have died because the filter was just sitting there for 10 hours with no water movement?
2. I way overdid it putting the Osmocote capsules in.
The problem: Out of, probably misplaced, pity I bought the last 2 baby girl Bettas from P... Sunday because I figured that they were better off with me than left in the store and I naively thought that I would have a cycled tank. So, I've been doing lots of water changes in little cups for little fish this week. I really want to get them into a real home.
Does anyone have any ideas other ideas about why my tank wouldn't be cycled or believe that one of my ideas is the reason?
Thanks so much for any help!
