Thanks for all your help!
Yes, but the sand is pretty easy to replace. You can also use a small diameter hose (e.g. airline) to pull out the cyano
. Since it tends to be thick, it will generally get pulled up before the sand so you might not have that much sand loss. have you checked your nitrates lately? Phosphate and nitrates both seem to fertilize the stuff.
Do you have good water flow over and around the xenia?
