This works if you have a sump Use an 1/2'' hose to siphon the sand into a filter bag placed in the sump (knee high panty hose works too) this way the water stays in the system allowing you to remove the sand. pour the sand in a dish pan and pick out any thing you want to save. where gloves as theres some freaky stuff living in it lol
Change out no more than a 1/4 of the sand at a time (4 weeks to finish) I used a 2'' PVC
pipe as a dam to keep the old from mixing with the new, by doing it this way the old sand can seed the new.
Most people create their own problems by not following the basics and refusing to stock appropriate to their system. Gregcoyote 2013
