I am new to this forum so first and foremost, hi everyone. I'm sorry if this has been addresses before but no amount of google answers have worked for me to date.
A little background, I have a 35 gallon warm freshwater tropical aquarium. It was my husbands as a child but we scrubbed it with vinegar and water for days before setting it up and replace all the substrate and decorations. After about two weeks of having it up and running with filter and all we started to add some fish. At first I only added 2 baby mollys(my fish at work had babies so I brought the survivors home when I found them do I did not overcrowd my 10 gallon at work). At this point everything is still crystal clear ( I filled it with water from the hose initially because after testing my home water everything was fine; we have a well, not city water) an the levels were perfect. We added fish slowly, a Molly here a play there a few Glass Catfish
, until i was comfortable with the fish we had knowing we had purchased livebearers that will likely reproduce. Everything was well for about a month until I tested the water one day and the ammonia had spiked drastically. It was at about 5.0! I was afraid for my fish so I immediately went to the pet store and bought ammo lock and a bacteria supplement. The levels never came down so I did a 25% water change, there was a small drop but nothing as significant as I needed. My fish slowly started dying off which broke my heart. I got another tank to move them to while I scrubbed my tank clean. Rinsed the rocks, replaced the filter with a bio wheel, and filled the tank with water I had purchased from the store. Everything was perfect, by this time I only had 4 fish left. I only fed 2 flakes each once a day for weeks and the levels spiked again! They are at 8.0 now, I've done daily water changes 10% for a week and nothing helps!! Help me! I had 1 Platy
, 1 Glass Catfish
and 1 corycat left and fear they will soon die as well! I've tried everything!!! I don't know what to do anymore, I have even started over from scratch and it spikes each and every time within a few days.
