A good sealant?

if your building a sump from scratch including the side panels then make sure you use construction grade silicone , silicone sealant wont do long term.

if its just baffles then sealant is fine

GE silicone I. Available at most home improvement stores. If you are not sure, just read the label and make sure its 100% silicone and doesnt have any mildew preventative substances in it.

I seem to remember all GE silicone now has mildew resistance and is no longer reef safe. If you could, can you clear this up name of the GE silicone?

The GE Silicone I - Window ver has no mold inhibitor in it. I have used it for my reef and I have had no issues.
But then again, its up to you. Everyone has their own oppinions and you can get the silicone made for aquarium use =p
