Re: quarantine tank question K deficiencies are typically exhibited through pinholes in new growth. Iron deficiencies range from yellow to downright sickly looking growth. A soil substrate has a fair amount of K, but if there is no substrate then the available K in the water column is expended very quickly, iron as well. Plants need food, it's literally that simple. Byte, fertilizing isn't something you just "do." The tank really needs to be set up with that in mind. I'd say either make it an aquarium, or break it down until you need a quarantine again, although I personally feel the practice is dreadfully overused, but thats just my opinion. |
