Hello Everyone. First time posting, but not first time here. I usually come here for information when needed. I need some help. We purchased a 10 gallon tank first week of july for my son. I told my husband at the time we need to cycle the tank before getting goldfish.....he did not listen..tank was only running a week before we got 4 small goldfish....(yes, I know...too many fish for that size)......so at the beginning ammonia was too high at 4.0 ppm
....I kept doing water changes to keep it down...I use PRIME with water changes......nitrites and nitrates were at 0ppm. Everything else was normal......then about 3 weeks ago....ammonia started to drop...its been in the range of 0.50 to 1ppm,...nitrites sky rocketed to 5ppm....nitrates were 0.....then 2 weeks ago nitrates started to go up but nitrites didn't really come down....I kept doing water changes and using prime...Well 2 days ago we lost a fish......from one day to another it looked healthy then the next skin was peeling off and then died. My question is ...is my tank still cycling or is there another problem going on? is my filter a piece of crap (topfin10)
Readings as of right now...(going to do a water change now)
I test with liquid and strips
Any suggestions? Thanks so much.
