How to disinfect freshwater stuff for saltwater

[BitFix]

Is there any way I can disinfect stuff from my freshwater tank so that I can use in my saltwater? Like my algae scrapper and/or my filter media. Also plastics.

Just rinse and use. IMO, I don't see any reason to disinfect.

I would disinfect with bleach a 1:100 dilution with cold water(water over 77 degrees causes bleach to degrade faster without added benefit). This will degrade proteins left behind as there are some things that can survive in both environments.

Let sit in bleach solution for 2 minutes. Air dry till smell of bleach is gone. For more porous things like rock this will need longer sit times and drying times.

I have some “Lace rock” that came from a lfs freshwater display. I soaked for a couple of weeks in bleach solution then freshwater with Prime for a couple of weeks. It’s now been drying for a month or longer. I’ve been afraid to use it because I would bet that the freshwater tank has been treated with copper at some point. Do you know if the bleaching process would have removed/neutralized any copper based medicines that may have been used in the past?

Bleach will have no activity on copper.

Very few people treat fw with copper compared to saltwater, ime there are more fw fish intolerant of copper than sw(gold fish come to mind). TTM and hyper salinity treat most fw parasites. Only thing i have used copper in fw for was snail removal. This has been my experience anyway.

Some ideas.
Run gac in the cycle bin.
Icp test the cycle bin water.
Buy a test snail to confirm, freshwater ramshorn snail can only survive something like 1/10th of the copper of common treatment dilutions.

If you are worried about Copper, soak the item in RODI with Poly Filter, preferably with some flow. The Poly Filter will turn blue if it adsorbs Cu.

I run Poly Filter in my sump permanently as a safeguard.

Good to know. Thanks!

Is there something that was in your fw tank that you are worried about?

Not really, I just want to make sure I don't transfer some kind of algae or parasite/animal that can survive in saltwater and hurt my animals

I would not worry about algae. There was a study done on atmospheric water droplets hundreds of miles away from the ocean that contained living algae from the ocean. there is virtually no way to avoid the few types of algae that can infect both water types. They are already present. The biology and chemistry of the tank is what stops them from being problematic not trying to stop their introduction
