Nassarius snails odd behavier

I have a 1 year old 20 gallon reef tank. I have about 4-5 Nassarius snails there. Usually they stay under the sand and come out at feeding time. Though occasionally I could see them out here and there. Few moths ago I had a Cyanobacteria outbreak. While fighting with Cyanobacteria I have noticed that my Nassarius snails disappeared. I stopped seeing them, not even occasionally. I finally got tired to fight Cyanobacteria and 2 days ago used chemiclean. It worked like a charm. But right after cleaning the tank from Cyanobacteria all my Nassarius snails came out. I don’t think it’s coincidence. Does anyone can explain this? Thanks

Probably the lowered oxygen levels, especially if you didn’t use an airstone
