Not necessary but I always do a "test-fill" for leaks and this will also rinse out any debris in the tank. Once silicone is cured it's good-to-go (as long as it's the correct type).Yet another question about silicone .... is it necessary to flush out the tank and do a few water changes after it is cured?
Yes I'd still recommend GE I over GE II, it seems to have a slightly better adhesion.If it releases the ammonia during the cure, after that, shouldn't it be safe??
Well put Mars23, just let it go...................1000's have been using ge silicone 1 for years without problems. how much more do we need do dwell on before we start asking for the caramel secret....
(isn't there enough proof to lay this to rest)
