Hey!

I have a 30gal tank which had a small leak in it so I've striped all the silicone off and am going to re-silicone it. Is there a specific compound I should use? I have lots of kitchen/bath/shower silicone which Im fairly confident is fine to use...but Ive heard that some better quality silicones have chemicals which can give off high levels of PH? Any input?

You should use aquarium safe sealer. It is sold at petcettra and other pet stores. It does not release any harmfull chemicals once it dries. It has a vinegar smell to it while curing and is set after 24 to 48 hrs....depending on temp and humidity... I used regular sealent before and had bad results...

kitchen and bath tend to have the mold resistant which is toxic.. i use GE for doors and crap that dosent have the mildew/mold resistance with no issues.. or you can go to petsmart and pay 30$ for a dinky tube... up to you if you want to take extra measures but as i said the GE I personally have found to be ok jut be sure it IS NOT MILDEW OR MOLD RESISTANT... it will say on the tube

make sure you get GE silicone I & not GE II. GE silicone II has mold preventives and leeches chemicals into the water. Also make sure you remove all the old silicone(new silicone will not bond to old stuff) & give ample drying time
