Is Ulva supposed to smell this bad?

[hhaase]

Just got my 4oz of Ulva today (chaeto still always out of stock). My basement now smells like an abandoned dock at low tide. A very very strong smell.

is this normal? It’s bad enough we changed dinner plans to get out of the house and let it ventilate. I mean BAD.

im ready to pull it all out of the sump and trash it. Or should it clear up quickly?

Just couldn't take it any longer, I've trashed as much as I could, god it smells just awful. But it broke into so many little pieces it's everywhere in the system now. Crumbles into little pieces if I even look at it, and now it's gumming up my pumps and screwing with the whole system. Going to be a long evening sorting all of this out.

Evening,

Sorry about the issue. I would check ammonia if you can and run some carbon to be safe. A water test may not hurt either to be safe

Probably not a bad idea on all counts, I keep a reactor and some carbon around for just such emergencies. Carbon should help with the smell too, which isn't so bad now that all the ulva is in the trash can outside. Outside don't smell too great right now though.

Had to get water flowing again first. This stuff slowed down both return pumps and I had to pull the screens and impellers to get the flow rates back up. I'll probably have to tear my skimmer down tomorrow again too. It's aerating right now but not skimming much, the air box is clogged. I also tossed a filter sock back on the returns to catch anything circulating through the tank as best as possible overnight. I'll swap that in the morning.

God what a mistake it was to buy this stuff.

Update:
Not showing any ammonia spike, though all I have for testing is API kits. So it's not exactly fine measurement abilities but at least would show me anything dangerous.

Pumps are pumping, skimmer is skimming, carbon is carbonating(?).

I can tell there is still some crud in at least one return pump, the overflow level is inconsistent. So I'm going to have to pull the impellers again soon. I just want to capture as many remaining chunks as possible first so that I don't have to do it a third time. My dual return pump layout sure is paying off tonight.

2nd Update:
Found the offending pump, at least the one that was making noise that sounded like it was straining Was the skimmer. Cleaned that and I think we're back to normal.

After a few days, things are still stable in the tank, no concerns at all. So other than really smelly and really frustrating, it doesn't look like there's any long term effects.

Kudos to Algae Barn and their customer service, by the way. I won't go into the details but I'm quite happy with their response.
