Changing out old sand

Need an easy way to change out o,d sand
Tank has been running for about 5 yrs but the sand was left over from a larger tank
It's been rinsed several times, tank was torn down and reset up a few months ago
Still getting nasty rust colored algae
Would like to replace with new sand

Typically we don’t recomend Messing with the sand bed at all. Toxins will be released that can while out a tank. This is assuming you have fish. You can siphon off small amounts from a single area once a week or so while you are doing regular water changes, till most of it is gone, you should be OK. You will need to monitor for ammonia and keep your nose tuned for hydrogen sulfide (rotten egg smell). be Prepared to do large water changes if you detect either.
