Review on LTWHOME Fish Filter Sponge Media by Kristy Esposo

I bought this foam after seeing pondguru's "Flush My Filter" for fx6. His suggestion is to replace the large white coarse scum with coarse and medium pond scum glued together. When the package arrived it became apparent that my black and blue lips were equally rough. Green is MUCH better than any other color. The two packs I bought don't have coarse-medium-fine. Now, compared to other customer photos here on Revain, I've come to the conclusion that the production is either NOT consistent or they're not getting it right anymore. I contacted Richard (Pondguru) and he said that the green color is similar to the medium he sells, so for those of you looking for this product to 'pump' your filter, he suggests to use either blue or black for coarse cleaning. and green is for the middle one. Hope that helps!
