protein skimmer

[ashley]

I am making my own protien skimmer and was wondering can I use a clear muti purpose silicone? Will it harm my fish?

The "hardware" silicone that is safe for aquarium use is GE Silicone I. Also make sure you let it cure for 3....4....5....as many days as you can.

 

[ashley]

Awesome thank you so much.

 

[redfishbluefish]

Please start a DIY thread on this.....I'm curious.

 

[ashley]

Ya for sure. Once I get all supplies so I can post pictures.

 

[chrisd]

Just curious, what are you going to use the silicone for ?

 

[ashley]

To seal my water bottles together.

 

[chrisd]

If plastic than I don't think it will hold.

 

[ashley]

Really why

 

[chrisd]

Silicone doesn't hold well to plastic and usually fails.
Weld-on adhesive is used for acrylic and would probably be a better choice.

 

[ashley]

And the weld on won't hurt the fish or anything?

 

[chrisd]

Nope, just fine. Like anything else just let it dry.

 

[ashley]

Thanks

Silicones are pretty tenacious. If you're actually using it as an adhesive, you might wish to try Momentive RTV 108.

Your welcome

Weld-on adhesive is used for acrylic and would probably be a better choice.

Weld-on only "works" for acrylic (polyacrylonitrile). The OP is using water bottles....either PETE or HDPE or some PE.

 

[chrisd]

Yes, it's used for acrylic and several other plastics as well. I don't know exactly what the op is using but I would suggest doing some research.

 

[ashley]

So this is the silicone I'm using

 

[chrisd]

That would be the silicone to use.

 

[ashley]

Yup
