"The silicone sealant will rot if the algae and mold growth is left untreated"
So even if you use black silicone, you may still end up with a flooded living room.
I have another aqua one that I have had for 5 years and there is nothing on the silicone. Only stained green from malachite green.
I have called the store, they are looking into this, and will get back to me.
