| No EK your dead on. If you see a patch of cyano or hair, you can bet the farm that thier is a Food source right under it that it is feeding on. the stirring of the bed and grinding with the fingers will break those bound and allow the bacteria (thats loaded with phosphates) the doc' (which are loaded with phosphates) the detritus (which is loaded with phosphates) to be suspended, with the syphon right thier to suck them out, you have now just broke the cycle and are exporting. You are taking away an ammount of the food source that is feeding the algae and so on. This my friend is exportation, just like triming the macro algae in your refugium, out of site out of mind.
