I have a 50g mixing tank, well.. rubbermaid trashcan with a lid, and a powerhead to keep it moving. I did a pwc
over the weekend, and the water tested perfect.... Today it has a musty odor. I noticed the smell after I put in a new ph, one that will pump the water to my tank (I had a smaller one in there, and I upgraded.
What would make this happen? Its a new ph, that I rinsed and ran in a bucket of sw
before putting it in my mixing tank.
I don't run a heater in the tank, except for about 2 days prior to my pwc
