So...I managed to kill floaters. Seriously...I did not know this was even possible. Duckweed, fairy moss, and salvinia. Deader than doornails. :P
All my other plants look great, growing well...even some finicky stuff like red rotala...not an issue. But the floaters...the floaters are dead.
Anyone care to have a go at what I've done wrong with these guys?
I use Tetra aquasafe plus, the tank was cycled with a sponge filter but is now close to being silently cycled by the plants (I just need a few more in there, sponge filter is still going), two bettas in a divided 20gL, a few pond snails, a ramshorn snail (who hitchhiked in), I added in some Flourish about a week ago for the first time, and I swear they started to look gross a day or two after, gravel substrate, two medium sized pieces of driftwood, both soaked but still giving off a little tannins which has darkened the water a little over the last 3 weeks. Two lights going, both hanging close to the top of the tank, about 3 inches above, 100 watt equiv. CFL bulbs.
Also had some additional amounts of the duckweed/salvinia mix and fairy moss sitting in two tubs until I could get some additional tanks ready. I added flourish in there about once a week, and I started to notice that after the second time they seemed to be looking worse and worse...so I dosed them again, believing they needed more nutrients, and I really think it's the flourish that's killed them. How is this possible?
Any information is greatly appreciated! I'm new to plants, so I'm sure I've done some stupid noobie thing. :P Poor little guys...I can get some more, but I still feel bad that I killed them. :(
