i just ordered a roll of that stuff. im gunna use it and give it a review. the pillows do an excellent job, offcourse theres a risk if you dont know what youre looking for. but the pros cant be ignored, the difference in water clarity using this stuff was excellent to say the least, i have a 1400 lph and two 700lph external filters. so i need sutn that lasts long and is cheap. i wasnt aware they sold pond filter floss on ebay so i cant really say which is best overall. so im going to review itBut the filter floss is made for FISH so you KNOW it is safe
also iu know its chaging topic, but i watched my rainbow fish lay eggs today, only to be scattered all over the place and eaten up by other fish lol
