Sha,
Thanks, I'll bump the CO2 up a bit and see if that helps. Yes, I have ten discus in my 85G, all between 4"-5". Leopards, Snakeskin, Snowflake, Blue Diamond, Yellow Sunrise, Phoenix and Red Melons. It's currently a discus-only tank, but I'm thinking about adding a few SAEs and Corys to help with algae control. I'm just hesitant because I don't want to visually detract from the discus. For me, it's all about the discus and plants
