My girlfriend has a 10 gallon guppy tank, it’s been setup for about 2 months it was cycled Ammonia 0 nitrite 0 nitrate 20 when we bought the fish. She bought some more fish probably too many to soon, and one died, nitrite was .50 and ammonia was 1. So I figured just too many fish to soon so started using prime to keep them alive, then the nitrite went to .50 and ammonia stayed at 1.
Here is what I don't understand, for the next week nitrite stayed at 0 and ammonia stayed at 1. How can I have a previously cycled tank have 0 nitrite and still have ammonia, I asked if she put untreated tap water; and she said no. So I ran out of prime still have Ammonia 1 and nitrite 0 after two weeks, so I figured all the bb was gone, and the tank was in a full blown cycle.
Here is the really strange part, I have a 55 gallon tank with sump, in the sump I have kept a sponge filter submerged in water but not running. So I took this out thinking hay my 55 gallon is cycled the sponge should have bb on it, I placed this sponge filter in the aquarium, hooked it up and did a 90% WC. Day 1 with this filter in the tank ammonia went from 5 to 1 or so and nitrite went from 0 to .25. So I was happy, I figured ok now it on a fast track to cycling again and the fish will live. Day two Ammonia not a 1 but not a 2 nitrite .25, day Three ammonia 2.0 and nitrite .25
How did this happen the tank stayed at ammonia 1 and nitrite 0 for 2 weeks, as soon as I put established media the ammonia shoots up?
I feel bad for the fish, I can't put them in my 55 I dont want to crash it by adding 9 new fish. It's my fualt I didn't monitor her fish keeping, I went throw killing fish in an uncycled aqarium with my 55G and a bad batach of bio spira.
