Hi, I currently have two tanks in my house. One 55 gallon with one oscar in it and a corner tank thats roughly 50 gallons that has 6 tinfoil barbs.
I'm guilty of hardly ever testing my water
I usually only test if it looks like theres something going on with the fish. Anyhow today I figured I'd do a test of each tank since its been so long(the fish seem fine)
The 50 gallon with the tinfoil barbs turned up normal results.. like 20ppm of nitrate no nitrite and trace amounts of ammonia (barley enough to even read it)
The 55 gallon with the oscar is what has me completely confused... Its reading no nitrate nitrite or ammonia.. keep in mind that both of these tanks have been setup for at least 7 months
I'm using the API freshwaer master test kit which is what everyone seems to recommend
