Thanks you guys....she does seem better today. It was suggested to me to put in some extra airstones which I did so she now has 3 seperate air sources coming and about 6-7 gals of water to play with. I also did a full system flush which returned only about 60ppm so not really any fert build up in the medium to speak of. I put in 6 new gallons of water today at about noon at 850ppm. Six hours later the ppm was down to 650....in six gallons of water. I have a feeling she'll make it.
