I'm afraid to drop the end below the surface level in the sump because I had it that way, sort of laying in the rock, but not blocking flow - it was quieter but then the end that connects to the drain bulkhead on the bottom of the tank developed a little crack at the seam and started dripping down into the stand. Thankfully, the eshopps hose had the same connector at both ends, so I just switched it around and the cracked end is now in the sump, but I was reading that it's recommended to keep the drain into the sump above the surface of the water or it can create back pressure which maybe helped that original seam crack develop on the drain hose. I'm afraid I will cause that again if I stick the hose back under the surface. Thoughts?
Interesting, never heard that on back pressure, but makes sense. I have mine PVC hard plumbed from bottom of tank into sump, so maybe the back pressure is only an issue on flexible tubing.
You could hard plumb it with PVC (not hard at all, could talk you through if you post a pic of your bulkhead)...or if you don't want to do that...you could let the return flow hit something that dissipates the water before it drops into the sump water level (filter sock, angled piece of plastic, etc).
If you hard plumb it, there is much much much lower risk of any leaks, hosing sliding off (yikes), etc.
Maybe someone else has better suggestion (or idea regarding the back pressure)...
