Urchin Spawning

[Blaise006]

Urchin has turned 100 gallons frag tank white. Does an established system need to take precautions over a broadcast spawning from long spine urchines?

If you're worried about it, overskim and replace that with new water.

Yes, an established system does need to take some precautions if a long-spine urchin (Diadema sp.) has broadcast spawned and turned the water white. While a spawning event itself isn't harmful, the sudden release of gametes can affect water quality and overall tank health, especially in a frag tank where water clarity and nutrient balance are critical for coral health.
