GHA on glass and Amazonia in the front
Got a GHA outbreak about 2 days ago and it's increasing. I increased the CO2 to yellow on the drop checker as I have no livestock yet and doesn't seem to be working. Light is a Ray 2 16.5" from the substrate. Substrate is ADA Amazonia with a layer of lava rock at the bottom with Osmocote+. I am dosing 3ml of PPS Pro every day. Ammonia level is in the 4ppm range because of Amazonia. Light is on for 11 hours a day and CO2 as well.
Should I do a huge water change? Overdoze Excel?
