Need help w/Clam

[mark]

wouldn't worry about the clam, the bubbles will come off easily

[fiorano]

the shell is there to protect the clam. so i would guess if you scrape them off the shell it should be fine.

I think they suggest "Gentle" so you don't burst the bubble releasing many spores into the water which will call more algae. The shell is tough.

Well....when I moved my clam from my old tank into the new, I didn't want to chance any unplanned hitchikers so I removed the clam from the tank water and scrubbed the outer shell with a plastic toothbrush to clean out any critter that might be hiding in a crevice. It didn't seem to bother that clam a bit as it was fine for 2 years after that treatment.
