Use old water or start fresh?

[2pts]

Everything I have read says not to use the old sand.

I would use the old water though.

I've always used old water, I try for about 50% so as not to shock everything incase the new water isn't quite perfect

Why not the old sand? It's not like it will be sitting in a bucket for days. Just scooping it up and transferring it in.

I would not use the sand. Your going to stir up a whole lot of what you dont want to stir up. But uae as much water as you can.

I have lots of nassarius snails, conches and a sand sifting goby who is constantly stirring up my sand.

Once you disturb the sand, it will release toxic gases as it holds nitrates and slowly converts it to good bacteria however its a slow process.

Ohhh... You beat me to the punch.

You stiring up the sand and a conch are two different things. How long has your sand been in the tank?
