tank sealant has film build up
It's been awhile since I've been on but maybe you guys can help me out. I recently bought a 3gallon tank and the silcone sealant on the sides of the tank have this whiteish film that keeps building up. I scrubed all the stuff off( it comes of real easy ) a couple of times and filled back with water ,only to find the build up again in a couple of days? Do you guys think there is something wrong with the silicone? the betta that's in their hasn't died yet? Any help would be greatly appriciated!
