I think I would maybe lower the temp to 80F. cooler water will slow her metabolism and hold more O2. Just a thought. If it were me I would also add 1 tablespoon of salt per 10gals and see if it helps. Keep us updated!! Don't want you to loose your blacky
I agree with salt. Maybe lowering temp will help too?
