deltec skimmer

[Skimmerking]

I had a 851 its a amazing skimmer and I used to use a return pump of about 3-4 gal that way the less you push the more skimming and the less chance that the skimmer will over flow. Remember its a external skimmer and it will and could have a chance to overflow. but with deltec its very rare in the 3 years I had mine they never did.
