substrate change

Are you doing it a little bit at a time?

It's best to do 1/4 at a time. Use a siphon hose to suck it out so that any anaerobic areas are removed from the tank without polluting it.

However, with a small tank I would remove all livestock, dump the substrate out, and put the livestock back in. Wait a week, then add new substrate.

Just thinking a siphon hose probably won't work with crushed coral. I didn't even bother trying with mine, just scooped it out.

Seems to be a lot of varying opinions haha...
