What is happening to my Frogbit?
I got this frogbit about 10 days ago. I've lost about 8 leaves so far, they all turn brown with this pattern on them so I trim them off. I can see this starting on about 5 leaves right now.
It's in a 10 gallon tank with some neon tetras, an oto, and a few cherry shrimp. I have a Nicrew light that says 11 watts/ 640 lumens. I am using a preset heater and the tank is consistently 82 degrees, which i know is a bit high. I'm currently using Seachem Flourish but someone recommended Easy green so I will be getting that next week. I have no lid on the tank to prevent condensation and I turned my filter way down so there's no current in this half of the tank. Any ideas?
