Has anyone experienced problems with the mag-float? I have heard that they can scratch your tank. Or would you be safe if you bought the glass mag float for a glass tank? Sorry if this is a stupid question, I used the search tool and found nothing. thanks.
I had one of these and the only time I had a problem with scratching my tank is when a piece of gravel got caught in between. Also I dont suggest using with a sand substrate. Other than that it is a good item/tool to have.
get the acrylic version even if you have a glass tank.
the glass version can and will make tiny scratches.
I have one of them, and because of the scratches,
(not from stuck gravel) I rarely use it anymore.
these diagonal scratches are a foot above my gravel
and are definitely as a result of using a Mag float.
the small sporadic white lines are moving bubbles.
