Yeah mine aren't anywhere near the actual stone.trahana said:I use the same. If your talking about water leaking into your air pump, I think that depends on your air pump placement. Mine is about six feet away from the first airstone so there is 0 chance of water running through the hose, as it isn't straight down.
How do you mean? A t and then control valve on the end of the dead end to leak air? Or am I missing what you mean?Mongo75 said:Most air pumps use a diaphragm to pump air. Putting an excessive amount of back pressure (control valve) on the diaphragm can cause it to wear out prematurely. Using a "T" and control valve is a better way to control pressure. It reduces stress on the diaphragm which will extend it's life somewhat.
