Oh no, I believe you. I was just saying I wasn't aware it would be like this. I've read some posts where people seem to have no problem with putty, and some "overflow"....but this thing looks like a volcano is erupting! I guess with it being brand new salt, sand, rock maybe all the putty didn't cure completely? Like I said when I put the skimmer in tap water, I get no foam, just bubbles not even up to the neck, so I guess it's pretty clear there's nothing wrong with the actual skimmer. I have a MarineLand internal filter I can fill with carbon. Should I let the skimmer just overflow back into the sump for 24hrs or just go ahead and do a water change with RODI? I've only run the skimmer for about an hour total or so but if it's the epoxy putty, seems like I'd do best to just go ahead and get as much out as quick as possible. I can direct the overflow to a bucket, but I think that will outpace how fast I can make RODI. Would letting the epoxy cure longer help? I used epoxy on only about the top half of the rock work. If I drain half of it, let it sit a week, would this help or am I just prolonging it? My RODI unit is a level below the tank, so water changes aren't exacty easy
