calk i can use?

wher ya from i know the petdepot sale the allglass sealent for 12.00 for 10 oz tube

 

GE silicone II 100% silicone window and door don't get the kitchen and bath it has a anti mildow agent that will leach. The window and door is fine thow I have sealed tons of tanks with it and never sprung a leak in 10 years and it is only about $5 a tube at wal-mart.

 

I thought you meant "Kalk" and I was confused

 

The ACE Hardware in Iowa City has aquarium caulk. I've used the GE 100% Silicone and the aquarium sealant both with good results.

 

Someone can correct me if I'm wronge but 100% is 100% so in my mind they are the same thing just one says aquarium so they charge dubble.

 

True - 100% is just that - 100% more profit for the "aquarium" variety

 

I guss I should read more closely then cause I thought the GE II did not have the anti-mildew but I just went and looked at the tube and by kriky it sure dose. So sence it is currently running in my reef tank sump for 7 years,agressive tank sump for 1 year,seahorse tanks sumps just set up also countless cichlid tanks over the years it must me safe as well.
