I was wondering if anyone could shed some light on what is going on with one of my tanks.
It's an empty tank, that I was going to use for a build soon. But I have run into problems getting it clean! There is what looks like water-spots and water line buildup all over this thing... and nothing I try works
I've tried vinegar, lemon juice, pure citric acid, bleach, and even CLR! Not to mention seemingly endless scrubbing with one of those green dish scrubbies... what IS this stuff and why oh why won't it come off? The citric acid worked just fine removing the scale from my roommate's cat water fountain. But it does nothing to my tank
I'm about ready to just toss some gravel in this thing and use it to grow out plants...
No picture because the residue is too hard to capture on camera.
