How Can You Tell If Bleech Is All Gone?

[EliteFishy]

I just washed my tank with bleech and water. How can I tell if the bleech is all gone and wont hurt my fishes.

usually i leave water running for 15 or more minutes, constantly flushing out the tnak, then i leave it sit with a major overdose of dechlorinator. With these steps i hvae never had a problem.

Can I use the chemicals for water changes to remove the bleech?

Yes, the dechlorinator, but use 3-4times dosage- Dechlorinator can not be overdosed(Well most of them)
