Haha I have never had problems with it. People always hate on the ASAon/off ones. I only have it because it was on my 2.5g tank and I wasn't going to buy a 5lb tank for an aquarium that small.
All the big leaves on the ferns had spots on them when I bought them and definitely were not that healthy and the bigger leaves don't look like they will recover. I have seen new growth from the rhizome though so I'm going to cut the leaves on the left one and then attach it to the driftwood since it is currently not attached to anything. The more central one has some spots but is not as bad as the one on the left so I'm going to leave it alone for now.
