Hi,

I noticed these areas on the bottom of my tank that look like water is under the silicone. There is no leak. Should I seal it? Should I do a full reseal job or should I add silicone on the outside where the plastic trim is. Heres some pics:

if it's not leaking, don't mess with it.
 
Well, it could lead to a leak. The tank isn't fully set up yet either. The area you see in the 2nd pic, if I press a little on the outside on the plastic trim I do see moisture/wetness.
 
then you are asking for it if you do not reseal
 
if you have to ask...than reseal

Sounds like you want to re-seal :)

It's easy (technically) but a little labor intensive. I've resealed a lot of tanks. I use a straight edge razor and cut out all the old silicon. Don't try to just repair a section, I think you will get better results with one "coat" all at the same time method.

Also, I don't think it's necessary to remove the glass panels, just cut out the silicon that's sealing the inside. After the silicon is cut out I use acetone to clean those areas. You can get this where ever paint is sold.

I use silicon 1 and try to get it all down quickly so it's just one coat. just a small bead in all the corners. Then I wet a finger and smear the glue into the cracks so it pushes out about 1/4 to 1/2 inch on each piece of glass.

It dries quickly but I usually wait a couple days before test filling, truly the hardest part for me :screwy:

I've never had a leak doing it this way. If I try to just cut out the bad section sometimes I get a leak, then I start over and cut all the old silicon out like I should of done the first time.

Good luck!
 
I could be wrong but from the picture it looks like theres a little bit of water between the glass and the trim did some leak there accidentally? if anything you could just see if you could remove the trim to check for an actual leak before you go through all the trouble?
 
Its still filled. I am in no rush just checking things out. I'll know in a few dayds if I should reseal or not. It could just be water trapped like you say.
