Hi,Finally I have decided to part with my trusty Deltec SC 1350. Got a bigger one and hence won't be using it. Better someone else make use of this amazing skimmer.It was running on a 90-100 gallon system of only acropora with 10-12 fishes and has been working flawlessly. I never needed to use GFO even.Below is the picture of skimmate that I get from it in 1.5-2 days. Will post pic of the actual skimmer once its taken out of the system and washed in vinegar.Add a BRS CO2 scrubber to take care of pH that connects to the air intake of the Deltec . It bumped my pH upto 8.1-8.4 .Prefer to sell as a package.Asking 250 shipped .Regards,Abhishek
