30-45 days at 80 degrees. However, if the urchins comes from a source where there is for sure no ich or other issues, I wouldn't qt if it you need them immediately.

What is it that you need them for to solve asap?

Algae growth in reef tank. Years ago I used urchins to hit the algae and they worked nicely. Have not used them for par 15 years.

The algae is kinda strange brown.. but not diatoms.... will put under the scope tommorrow.. take a good close look.... the filter floss is brown like after a few days ... I am thinking this might be due to light spectrum.. when the lights were only one for a few hours a day .. i tried this for a week... was more green...

If your worried about ich. It has a period where it goes dormant and requires fish to go on. You could do a 7-14 day qt on them likely or less with no problem. Urchins can get worms, but only worms that affect the urchin itself.
 

Do you house a "Reef Safe" Angelfish in your reef tank?
