So I've bought a couple of things to make a very powerful and cheap canister filter and started using silicone last night around 10pm. And now it's 11:50Am. Does anyone have any experience of if the silicone dried out/cured and used tested it with everything ok? Please let me know. Thank you mfk.
 
What is the typical cure time (drying time) for silicone caulk?
A 3/16" bead "normally" completely cures in 24 hours. The cure time could vary depending on the moisture in the air. Lack of humidity will make the curing process slower. If the product shows some sign of curing, such as a change in original consistency, it should cure but might take longer than normal. It might take up to 48 hours for caulk to cure under cooler or dryer conditions.

Typical Properties

GE Silicone I* caulk:
Tack-free: 30 minutes
Water exposure: 12 hours
Cure time: 24 hours

If your not in a hurry wait a couple of days .... :)
 
dont usee silicone 2 it will kill your fish because it blocks out mold and you need bacteria in your tank
 
Well I have 100% silicone sealant and it says 12 hours but you know some things lie. It's a red and white tube. On the back it also says it's excellent for marine applications. What do you guys think?

I think you might end up spending a dollar to save a dime.
There are very few "aquarium safe" silicones.
The bulk of what you get at the hardware store will slowly kill your fish.
Just me, but I would save money where I knew it would have no effect on the fish.
Get the right stuff and you have no worries, well, other than your DIY can spewing water all over your house.
 
Ive tested it with water for about a minute and with the powerhead connected to the tube and canister and tHere Are no leaks so far. I will test it out with rosey reds or feeders and see hat happens. Thanks for the info everyone. Much appreciated.
