Im swapping knobs to my zillion 21. Why did the knobs come with some many parts? the problem is that either the fitment is too loose, or i cant tighten the screws all the way or the knob stops spinning and then they come loose when fishing
I got some new corys, one has died and this one seems ill, do I do a water change or will that make it worse because I can't heat the water before I put it in Posted by LegitimateBelt8463
