Do I need to wash Lapis Lustre sand?

[FlyingChicken]

Is it clean?

Will it pollute the water if I don't wash it before putting it into the tank?

Washing 66kg of sand is no joke bro...

I didn't the last time I use it. Just make sure you topup the water slowly when doing so.

I didnt wash them for my 6ft neither. They should be clean enough without additional wash needed

Lapis is really clean. We used God knows how many bags for the 9ft tank we set up for Teo, but the water was clear when we topped up the tank on the same day.

Same for me, I do not wash Lapis sand when I used them.

However, I will still caution you to pour slowly to minimise the fine sand-dust from flying about. Keep children away and let the dust settle (15 mins?) before you resume working on the tank.
