So I just siphoned my first all grain batch with my auto siphon. I don't know what I was doing wrong but it just didn't work as I had planned. Should have been a simple task but I think the hose was to long so I cut it shorter. When that happened the beer was splashing in the bucket. Nothing to crazy but I am worried I might have ruined my beer. Looking here for anyone who could hopefully tell me I didn't ruin it, don't sugar coat it just give me the truth.
The beer like I said was splashing but not uncontrollably, it just created a lot of bubbles on the surface of my secondary fermenter.
I quite like the auto-siphon. Been using them for years because they are so convenient.
One trick is (as you found out) is to pay attention to the hose length. Ideally it should be around a foot longer than the distance between the bend of the cane at full extension to the base of the destination bucket/keg/fermenter. This will keep the hose in contact with the bottom of the vessel but not leave too much extra to wrap around the inside.
Since the difference in elevation between the two vessels is something you choose, it's easy to vary the available hose length using your existing hose just by raising or lowering a vessel until you're pleased with the result.
Your beer is likely fine, especially if it's a style that'll be consumed rather quickly. Like the hydrometer, consider it another educational experience. I've broken plenty of those.
Most importantly, congrats on your first AG batch!
