I just added what is supposed to be reef safe a chemical - Cyano solution - to clean out the red algae/crud. My water and tank were perfect and I was told it was safe but now my beautiful urchin has lost all his spikes and I don't know if it will make it. I did a 10 gallon water change to my 90 gallon tank and turned the protein skimmer back on but I don't know if how long it will take to filter out and if it is too late. Would it be better to put him in a bucket of clean water with a heater and bubbler or would this be a bigger shock than leaving him in? Anyone have any ideas?
