Safe to sink my dw?

[SgtKumar]

Hi all shifus, some pro advice needed. I have a couple of drift wood which is from my previous tank. The problem is that last time smth went wrong with the water and it wiped out my comm of 2 kels, 3 kongming, and 1 rtc. Survivors are transferred to main comm. I have since soaked the dw in water for 3 - 4 weeks in a tub. Occasionally pouring hot water on e dw.

Is it safe to sink the dw in e main comm tank now?? Scared theres smth wrong with e dw.

Thanks in advance for the advice.
