CalmedByFish Posted August 12, 2021 Share Posted August 12, 2021 (edited) I have a 20 gallon, about 1/2 full of healthy hornwort to combat and prevent green water. But I currently have green water. Been 2 weeks. I'm keeping the light off for now, except a couple hours of very dim per day to help the fish find their food. I've decreased the adult's feeding from 2x to 1x per day, though I shouldn't fast them since about half are preggy, and I can't reduce the feeding for the tiniest fry. The tank is bare-bottom, with a ton of MTS, so no food is getting lost. (I also watch to make sure the filter doesn't grab it.) In the next few days, I'll put a few of my extra neocaridina in there, since they'll help re-process the MTS poo. My current question: Nitrate is ~5. Do I add Easy Green to help the hornwort, or leave nitrates low to starve the green water? Edited August 12, 2021 by CalmedByFish Link to comment Share on other sites More sharing options...
