First off, I'm extremely new to fish keeping. I've had my tank for about 2 months. I got the tank, filter and about a dozen fish off a friend who was moving. I failed to do any research before getting the tank and all the fish managed to die in about an hour...I still don't know why exactly.
Following that tragedy I started obsessively researching. I now have 9 happy, living fish (4 longfin zebra danios, 4 Corey cats, 1 dwarf guorami). The tank is 50 gallons and has a Fluval 306 filter. I test the water frequently and things have always been good (pH 7.8, ammonia 0, trites 0, trates 0-20). I do weekly ~10-20% water changes. I got my last fish about a month ago.
I did a PWC on Saturday, regrettably I didn't test the water until Tuesday because I was thinking about adding more fish. pH was 7.8, trites 0, trates 10-20...Ammonia was 8! I tested the water twice to be sure. I also tested my tap which was .25. Immediately did a PWC and tested the water right after...it read 0. Can it really change that fast?
Tested yesterday and it was .25, did not do a PWC. Tested today and it was between 1 and 2 (I have a tough time with the color chart). Did a 20% change. Ammonia is now .25, nitrites are .5 or 1 (seriously how do you read those charts accurately?).
Is the tank going through a mini cycle? Any idea what may have caused this? I don't think I over feed, but sometimes my roommate does it for me so he might. There was some dead plant matter that I found, could that be it?
Also, it's time to do monthly filter maintenance...should I go ahead and do it or wait until things are back to normal?
All the fish seem happy, at least. Any advice would be much appreciated!
