Seachem Prime, tapwater

[PebbleSpotting]

I guess this is a science question, because I suspect it's more chemistry than anything.

Tank full of fresh tap water. Crucuially no substrate, no filter, no nothing. Just a bit glass cube full of tapwater.

If you added Seachem Prime at the recommended dose, would you expect the water to turn cloudy?

After how long did it turn cloudy? Was the water cold like tap cold?

Been using prime last 2 years and not witnessed that.

Hmm, there must besomething that you haven't made us aware of.
If it went cloudy straight away then either the water was cold or you didn't shake the Prime (or you've added way too much ).
If it went cloudy later then it could be that you have a bacterial bloom as the cycle tries to get started. I doubt it will get far very quickly without some sort of filtration and no ammonia source...

Chloramine would be an ammonia source…

[plankton]

True, the Prime would turn it into ammonium which would start it but without further ammonia it would run out of steam....

Oh, absolutely - there's a big pile of unseasoned spiderwood in there too. What I'm trying to figure out is, is it the spiderwood or is it the prime? To be honest, I think it's a bacterial bloom, but I wanted to make sure this wasn't a known thing with that water conditioner. That's why I phrased it more as a hypothetical question.

I'm going to run it again with just the prime, no wood, and find out for sure because I'm curious.

(Cold water from the tap, no heater, unheated room, couple of days between when I filled it and when I next looked at it, 360L-ish of water to 10ml of Prime).

Bacterial bloom if it was a couple of days.
