I tried filter floss, it doesn't work, it block the water flow. I need something much more thin. Maybe "AquaticLife 50 micron non-woven polishing pad (1/12th inch thick)"? Need to try it. Or maybe 100 micron pad, it's much cheaper (13$ vs 18$ on Amazon).
Something else is wrong with your water chemistry that the brown algae is taking over.
Just as information - Pensacola PetLand sells AquaticLife micron pads 26" x 30" (5.4 square feet) at the following rates:
300 Micron: $8.99
100 Micron: $9.99
50 Micron: $10.99
The prices quoted from Amazon are more than Petsmart sells them for at retail. Petsmart is usually at least 50% over Amazon prices ....... so something is wrong there at Amazon.
And, no ....... don't try 50 micron pads over the drip tray. Just for fun, since I have scraps of it, I cut to fit 100 micron aquaticlife pad and yes ...... it worked. But no better than just taking the original old pad and squeezing it between my fingers under tap (yes, tap) since I have so much excess BB).
Also note to everyone using aquaticlife100 micron polishing pad: I said this elsewhere that there are no directions on the package, but it does have a flow pattern. One side of it feels like felt ........ that is where the incoming water should go. The "finer" side feels like it is plastic coated and takes out the smallest particles.
When used with the correct flow pattern, the 100 Micron AquaticLife pads FAR outlast the OEM polishing pads. And the water is so crystal clear it is incredible.
Also, I have found the 50 Micron pads I have been using on one of the C3's in my 38 gallon don't make the water any more crystal clear at this point than 100 micron pads ....... since 50 microns is less than the human eye can see.
