how do i take care of chaeto in terms of if i need to feed it and what products should i use, like do i use the same iron that would be for fresh water plants? i just went to the fish store and ran into chaeto that i just was thinking ordering online for nitrate problem that i've been having. i'm gonna go and get little aquarium lamp for it, with helogin light bulb. i don't have lots of it for now, but hope it will grow fast. the store people didn't know anything about it besides that it's micro algae, it wasn't really for sale, they just had it.
