this is a nice DIY for scrubbing GSA on glass panel of my new scape tank.

item used.
3M micro fiber sponge ($4 to $5)
broken long tweezers ( free )



1) cut out a 2 cm by 1 cm size from the 3M microfiber sponge (depend on indivdual)

2) stick the pointed end of the broken tweezers through the cut out sponge in the centre ( try to stick in slowly as not to rupture the sponge )

3) use it any where which is hard to reach.



This way, even if you have foreground plants covering the glass with GSA, you also can wipe them clean without uprooting plants like HC or hairgrass. Don't have to worry about magnetic glass cleaner scratches your front panel as the 3M microfiber sponge do not scratch the glass.
