Silicone...Which Type To Use?

[LoneStar]

I'm going to be making my sump/fuge today in a 30 glass tank. I have some plastic I am going to be using for the dividors and I need to know which type of silicone is safe to use? I don't want to pay a bunch for the small tubes they have at Petsmart and what not... Is there anything I can get at Home Depot that'll do the trick without being too toxic??

ge silicon I is what I used

100%

If you go to forever pets they sell the silicone used on tanks.

Just out of curiosity. What is the difference between Silicone I and II? You can only find I in the large tube for a caulk gun where II you can find in the smaller tube. Both say 100% silicone on them.

Then you have other brands that aren't listed as Silicone I & II, just 100% silicone.

I am not sure which one, but the Kitchen and Bath has mildew retardent in it.

Home Depot has the Aquarium Silicone on for $1.50 a tube.

ok bought the kitchen and bath GE 100% Rubber Silicone Type I at HD last night and set 2 pieces of ABS plastic in my 30 gallon sump/fuge. Worked great! Just gotta let it sit outside a bit so the smell with disapate. The plastic is holding strong.

Kithcen and Bath have mold inhibitors in them which is a fungicide and well kill your tank. At least that is what I have read. I used the GE I and I am leak testing it today.
