I have some hair algae trying to grow in the middle of my zoos....not bad, but barley visible......my snails have started to crawl onto the zoos....will this hurt them, or just clean in between the polyps for the zoos?
IME Well I have 2 bumble bee snails and they craw in and out of the zooz eating all the crap on it and cleaning them. The zooz close when their cleaing them nd when their done the zooz open up withing 3 minutes. The bigger snails I would watch out for. You should be fine.
