get two srong magnets anywhere
place the "wet one" in a ziplock baggie

choose the scrub cloth of your choice for the wet side
Choose a soft cloth for the dry side.

this lets you do it with as big a scrob cloth as you like, and any surface
I like the natural bath sponges
my big tank is only 50 gallon, but the little magnet things are too lame for
me to want to waste time with then

Rick,

Magnets appeal! But I haven't found any in the UK that will work through
1"
acrylic. Can you recommend any UK or US magnets that will work with 1"
acrylic and do a good job?

Hi,

I am troubled by difficult to remove diatoms (algae) in my lake Malawi
setup. This is made worse by the fact that it is a big tank 6ft long
5ft
deep and acrylic!

Anyone any suggestions/tips on shifting these without scratching the
acrylic? I'm currently using a Kent pro scraper/mop but the scraper is
occasionally scratching the acrylic and the mop wont budge the diatoms!

tia,

Sky

if it is the stuff that is easily removed you could either try one of
the
algae magnets but be careful you do not pick up any grit at all or it
will
scratch the tank terribly or perhaps a rubber squeegee.
