450g total volume. I had the skimmer running with no problems before putting the display tank online. Right after I put it online it knocked down the skimmer head and I saw a oily residue on the surface of the water. Also the inside of the spaflex felt a bit slippery when I checked the scrape pieces that I had left over.GreshamH said:For what tank volume? New tank? New skimmer?iani said:I used about 50 feet of spaflex on my tank. I can tell you there is some sort of residue in the spaflex that knocked down my skimmer head for about a week. My friend told me it was probably the releasing agent that was used when manufacturing the pvc.
I used 200' of 1"....100' of 2"....40' of 4" all on a 680g and had absolutly no issues. That was a quarter million dollar install.
