Thanks Kelly
I might bring all the coral from this tank over to you tommorow if you will be around.
Not sure what will survive but I should be able to tell soon enough.
To be honest after posting this I took measurements of the space I have and am considering a 4ft tank to take its place and perhaps clean this 50 gal and throw it in the basement as a hospital / quarantine tank.
Maybe a larger system with top notch filtration would of been able to avoid this.
