hey Styx...so gald to be able to read and see what your doing while I have my coffee...My 300 sump has been growing. Got rid of the old 60inch and converted my old 140 acylic into the new sump and design...The old 140 was about 20 years old and so I need more sump room so saved cash and used it for the new sump. My old sump I made was 1/4 inch thick, never again use 1/4. making sumps now for people with 1/2 inch as minimum. at the prsent time shopping for a bigger skimmer. looking at reef octopus regal300sss or sro6000. My current reef octopus 200int is too small for the 300 with all these tangs since they got big, so gonna use the 200int for the ozone and bio pellet water discharge.. Any thoughts on a big skimmer for my 300, I am looking for it to handle 300 super heavy load,,,,
