Hi All

We have finally started putting the hardscape in my tank. I have been super Cyanoacrylate super glue and an aerosol activator.

All going swimmingly, until I look at the spray can and it says it is toxic to aquatic life with long lasting affects! Balls!

I wonder if anyone else has done the same thing and if you had issues? I am hoping that when the solvent and propellant have dried/evaporated, it is ok?

I have seen so many people using this method that I didn't even think to check the bloody bottle :/

This is the activator in question https://www.amazon.co.uk/gp/product/B0C69LDK56/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

Hoping I don't have to throw out a huge and perfect piece of bog wood.

Thanks
Aaron

The ingredient list is a bunch of variations of hydrocarbon chains and cycles with no other functional groups. These will all be reasonably volatile so will evaporate quite readily. I wouldn't want to breathe them in, but I don't think they will stick around long term. Let your hardscape set up completely and then air out well - maybe have a go with a hairdryer on low heat. Then give it a good thorough rinse (or two) and I expect you'll be good to go.
 
It will contain N,N-dimethyl-p-toluidine. The molecular formula is C9-H13-N. It has a high boiling point of 215 degrees Celsius and is a liquid at room temparature, plus it is common commercially, so I do expect it will evaporate over time. Do not use a hair dryer. It is already acutely toxic and should only be used in open unconfined places, so to use it indoors again in the future I might consider an A2-rated face mask and standard PPE like nitrile gloves. The problem with evaporation might be the molecular forces holding this molecule in the wood as opposed to letting it evaporate, but just work slowly, with gloves, keep the window open, and test the tank with some daphnia before you introduce livestock.

Interesting. So what does it do once it reacts with cyanoacrylate? Because that’s what people are doing with it. Ignore the use in an aquarium for now, the main use I see this for is mitre-bond by joiners. This product is <1% N,N-dimethyl-p-toluidine. Here’s the SDS:
