Algae scraper

I currently have a 32 gallon biocube, when I purchased it, I also purchased the magnetic biocube algae cleaner. I think it sucks badly lol, I probably need a magnet cleaner that’s rated for glass thicker than mine. The magnet I currently have is rated for 1/4 inch which is what the glass is.
I can see the lines of the Velcro if I look at the glass from an angle. It’s not scratched , the magnet is just not doing it’s job. Also, the glass isn’t covered in algae, just a slight haze of it.

 

Magic eraser original with no chemicals added or genetic melamine sponge cleaners from amazon. I get 70 of them for about $13.
I use one to wipe the sides and front glass of my tanks during weekly WC. Keeps it sparkling.

 

Im looking for something magnetic, that way I don’t have to my entire arm into the tank in order to clean the internal glass.

 

I use this one, works well on my 5ft, 6ft and 63L, but I only really need it on the 63L as its a crayfish tank and can't have plecos.

I purchased a mag float last night, I have glass but I prefer the felt pad that’s used for acrylic. The Velcro looking pad for glass I feel it has scratched my glass.
