Dino killing fishes?

[OsciBosci]

Hi there! I have some problems with Dino, probably Ostreo. Today I have decided to suck out all od the Dino from the sand (a lot of). After that, most of my fishes started to heavy breathing. Almost 1h after the cleaning Chromis Viridis was dead, few ours later Ecsenius Bicolor was also dead. Is it possible that Dino released toxic into the water and it is killing my fishes?

No expert but by sucking and disturbing the sand bed it could’ve released gas and elevated or cause ammonia/nitrite spike. Hard to tell without your tank parameters and layout.

Apply airstone, run carbon and do a water change

Ok, but are my suspicions correct and have toxins been released?

Hard for us to jump to that conclusion without knowing anything about your tank.... tank age, number of fish, parameters, tank size..... it could be the cause or it could be coincidence.
