i was having an issue with root rot and algae, so i was told spray peroxide. i tried a diluted mix which didnt work too well, i then sprayed a straight peroxide on the algae and roots while also clearexing the day after. i came to find a bunch of dead plants, some of which the whole stem was white as bone. the new growth looks like its coming along kinda well but the rest of the plant looks dead is there anyway i can bring them back to life? someone please get back asap... THANKS
