I will yank the bladderwort out asap.I just posted to your other thread. I thought that white was just your exposure! I think you need to start dosing ferts. with iron, & traces. (Why aren't you dosing?..)
Pull the bladderwort out. It will take over. It's not good.
my lighting is a 27watt home depot desk lamp specialYou must have high light or your UG wouldn't be growing. With high light you need ferts. I don't know what to say about the soil. I know people use it in El Natural tanks. I have read that people do a mix with soil, capped and high tech. Is that what you're doing? If so, you still need to dose. And you need to do w/c. Do you think your plants have used up the nutrients in your tank? Did you enrich your soil with something, like Aarons mineralized soil? I know he doesn't dose with that except for K, I think. I guess it depends on what you put in your soil. Even so with high light the plants grow fast and use up the nutrients. That may be what's happening.
ingg,Yikes... let us know how dosing a soil tank goes. I was taught flat out not to do it unless absolutely needed in one specific nutrient, and then to do that nutrient very very sparingly.
I don't dose mine with the exception of .2ppm potassium once in a while - so next to nothing.
Downoi is taking quite a while to establish, but I can't tell if it isn't coming back, or if the cherry shrimp are just eating the new growth....I suspect the shrimp though, as others have grown it fine in soil tanks.
