I have looked at a few posts involving this type of scraper.

It has been my experience that only a metal bladed (I have glass tanks so, if you have acrylic, don't use this) scraper takes algae off once it is visible. The magnetic scrapers don't seem to make a dent.

My question: would the magnetic scrapers be good to take off the invisible stuff on the glass (the film is the 'anchor' so to speak) before the algae really takes hold and showing: something like a preventative. Namely use the magnet scrapers before the algae become visible.

thanks

Most magnet scrapers like the mag-float use scrubby pads and not any kind of blade so they suck when compared to bladed scrapers.

If you want a bladed magnetic algae scraper look up Penn Plax they have a magnetic dual blade scraper one half is black the other is green. I've had one my parents bought well before I started this hobby and its well over a decade old and going strong. Definitely the best algae scraper I have ever used it cuts through very heavy algae.

Yes, the magnetic scrapers are good for removing the film but suck if you have algae such as green spot algae that has taken hold. Myself, I just went back to a good ole scrubber pad and elbow grease. Lol

I use the regular magic eraser. The one without any added chemicals. I read the msds safety sheet on them,so I know that they are inert. They can get a bit beat up if you scrub too hard. This will cause them to fall apart. Just make sure the fish do not eat the small bits that come off.
