I freshly cleaned old dead rock with bleach, and than used dechlorinater until the strips ran colorless.

Is it normal to have a bunch of suds / foam when we pour fresh water into the bucket of rocks? It is a significant amount.

They are highly inaccurate. I would suggest a pool chlorine test if anything, otherwise a good soak in the sun and water will eliminate chlorine very quickly

I would not assume all are highly inaccurate, and, of course, the need for extreme accuracy is not high when chlorine is the issue.

What brand dechlorinator?
API Tap Water Conditioner

I assume they are useless because the lowest amount of detectable chlorine on the strip is 10ppm, and anything lower could still be harmful but not showing up on the test strip. For example our tap water which definitely has low amounts of chlorine / chloramines is not showing up.

Which means that is the wrong test strip to use. The ones I posted are plenty low enough.

Still wondering about this.
Personally after bleaching I put the rocks in a bucket of tap water with a powerhead for a days then, then finally in a bucket of rodi water for a few more days, then it’s good to go. Dry or don’t dry it doesn’t matter.

It's often claimed to be true, but water in rock pores likely doesn't get any sun or drying, and I've not seen any data on how long it takes the oxidizing species to dissipate.
