What is the best way to keep flexible tubing (1/2 or 3/4") that hangs over into a sump from moving. What do you use to secure it to the top lip of the sump, so pressure doesn't move it or want to make it act like a water whip.
For small tubing going into the sump I've used rubber bands and something heavy/save to the tank and rubberbanded the tube to the object. Works like an ancor.
If there happens to be any pipe or other larger hose there you could zip-tie the 2 together.
All the previous posts seem to assume that your tube is coming vertically down (from owerflow for example) and is fed by the agravity alone, in which case some added weight (a bit of extra length would be sufficient for that) or binding to some other hose will do the trick. If, on the other hand you have a problem, like I did, with feed that is comming from the side/below and is attached to much stronger water flow source, like a pump (topoff in my case), then you are probably looking for something to anchor it over the walls of your sump or tank. For a sump, where I can go ugly, I have simply clamped a plastic clamp on the on the top portion of my glass, and then using simple plastic cable ties (anything that can tie the pipe to the clamp and will not leach chemicals or rust), I fixed my pipe to the clamp.
