I did that once with a screw. I went to the auto parts store and got magnetic pick up tool. It was cheap, didn't care if it rusted afterwards.
Tank looks awesome.
That is what I originally tried. I put a bunch of magnets in a bag and string and lowered it through the back of the tank. I could not get it at all. After 20 minutes of frustration I decided to test another washer and of course, it wasnt magnetic. SMH
That's when I had no choice but to dismantle my rockwork. Lesson learned on that one.
Thank you! Loving the T5's so far.
