silicone

[Titus77]

I'm making a filter/power head cover so that nothing (anemones) get sucked up, and was wondering what silicone is reef, invert, fish, and "liverock" safe. Please specify what brand/type/name.:D

-thanks

GE Silicone I for windows and doors (no mildicide or bio agents) will be just fine.

[Titus77]

would GE Silicone 2 work?

[jeffb3t]

#2 has the mildicides in it go for the #1 and smell it. If it smells like vinegar, you got the right one.

Actually, #2 doesn't necessarily have the anti-mildew additive. Only if it is for bathrooms will it have the anti mildew chemical. So even #1 for bathrooms will not be reef safe. MUST BE FOR WINDOWS and DOORS to use in an aquarium!
#1 works better for plastic to glass seams and #2 works better for plastic to plastic seams.

Ge silicon II windows and doors does not contain mildew inhibitors. I checked with GE.

I used GE #2 for my sump (plastic to glass) and I havent had any problems for the last year or so. :D

I think it depends on where you are in the country. Last week I went to Lowe's and there was not a single GE Silicone II that did not have the bio??? something or other in it. So I got silicone I for windows and doors. The reason I looked at the others was because I wanted black silicone and Lowe's only had black in II.

I saw the same thing at Homer Depot last night. It all has Bio labled.

I did find GE Siding and Trim 100% silicone which has the highest (#10) adhesion rate to plastic and polycarbonate.:)

[Titus77]

yea, I found a #2, and it said "not for: ..., or aquariums."

[nitratesucks]

I just went through the same thing at home depot all said not for aquariums. Then went to crapy tire and they had one kind made buy or packaged buy mastercraft. It said right on the label that it was (Ideal for use in aquariums).

[Titus77]

whats the name,brand, and price?

[nitratesucks]

Sorry i forgot you were in the US. This is a canadian product. As for the price. I can't remember, guessing at about 10 bucks. The name is mastercraft. Window and door.

[Titus77]

oohh...ok.

At Lowes all the GE II here has the anti microbial, all the DAP brands did as well. Any of the GE I did not and didn't have the "not for aquariums" warning.
:cool:


The "vinegar" or acitic acid odor is not a determining factor, as far as I know, all RTV silicone sealants available to the consumer use acitic acid.
:cool:

Which silicone is the most heat resistant?

[hllywd]

Some is good to 4 or 500 degrees, I think I have a tube of Permetex brand that says 450...

[gotdibz]

i used this ..and no problems with it http://i35.photobucket.com/albums/d193/yieyo/filter.jpg

[hllywd]

I've never seen that... look's like a GE tube??? That should be the ticket for building partitions in sumps as long as it doesn't have the anti-microbials... cool:D

[gotdibz]

thas exactly what i used it for...no problems with it and it is GE
