So far... good
it worked well on hair algae on rocks and in side corals. It also worked well cleaning the sand. I'd recommend to use a rechargeable 9 volt battery, because when using it with a battery it will quickly drain the battery. However for home use it is also AC wall adaptor operated, so having the ability to use a battery makes it portable for like if you were at a hobby showing.
