It should be fine as long as it does list cyanoacrylateIs Loctite Ultra Gel safe for a reef tank? It doesn't give an ingredient list but does say "contains Cyanoacrylate".
I was able to find the SDS listing the ingredients. But to be honest I don't feel comfortable with giving my opinion on whether or not this can be considered safe. Maybe someone else knows more about siloxanes and the third listed ingredient.
Edit: I compared the linked SDS to the SDS from Seachem "Flourish Glue" and Arka Coralscaper. Both do not contain anything besides (m)ethyl-acrylates and cyano-acrylates. Maybe there is a good reason for this. Better be safe than sorry and get a product that's meant for reef tank use.

My short research says yes it is Cyanoacrylate based . Seachem does as well and they state theirs is. However it does not say so on your picture so who knows what else is in it. Why take a chance . I would NOT

Just keep swimming
Just go to the dollar store and buy their gel tubes
You are all recommending things you know nothing about as you have no connection to manufacturing companies and do not know the contents. I would suggest keeping your tank crashing opinions to yourself. Sounds mean but sorry it is a factual situation . Do you give financial advice out too ?

I use Locktite gel for automotive. No issues and I've found it holds much better than any other glue I've tried. And I have tried alot of them.
My favorite glue too...i have bought tons by now. Cheap cheap

The listed siloxane (CAS 67762-90-7; Dimethyl siloxane ) doesn't look to be particularly hazardous. Siloxanes are the building blocks of silicone adhesive, and there are more and less toxic ones that are gradually being regulated in some countries but still used in others including the US.
CAS 119-47-1 is a reproductive toxin and is particularly hard on aquatic organisms. Whether the concentrations at issue are enough to be concerning, I don't know, but if apparently safer alternatives are available it would seem like a no-brainer to use them.

Using it 5 years the gorilla glue gel (green top).
Great stuff. No worries. If you can “wet” the glue before putting in piece that really helps.
Easy to use, half the price, solid and quick bond.
Just make sure you don’t drop any in the DT water directly. It will ball and can be mistaken as food.
And the results of that can be catastrophic.
I always use ball of epoxy with super glue on both side...one side to frag other side to reef rock....Never moves again until i break it loose with a screw driver
I have tried every brand of super glue and they all work no problemo.....you dont need expensive reef branded over priced glue
