I am constructing a small DIY canister filter for a fry tank and was wondering if anyone knows of a good brand of sealant or caulk that i could use to seal up some fittings?
Use %100 silicone caulk, and make sure you let it cure for 24+ hours. 48 hours is really best. Even if it says silicone caulk make sure you read it, some have added chemicals that are harmful to fish.
That's neat, I always thought about doing one. Good luck, and please post pictures!
