marine safe silicone?

[Jritter02]

Is regular caulking ok for fish or is there something special I need to buy? And can I get that from home depot or something?

What do you plan on using it for?

[AdamNC]

Unless it says Safe for Aquarium Use, I would not use it.

[Jritter02]

Building a sump so I need to put some chambers in it and seal it with silicone.

I used this (http://www.homedepot.com/p/DAP-2-8-oz-Silicone-Aquarium-Sealant-00688/100128841) silicone in my sump. Just give it time to dry, I waited about 2 days just to be safe.

And believe it or not I found it cheaper at a local petco/petsmart, can't remember which now, for about $0.50 cheaper.

GE1 windows and doors is what many of us have used over the years, any HD will have it.

That's guys. Gotta get the process started. :)

I use GE silicone 1 or 2 just make sure its clear not colored and for "windows and doors", "not kitchen and bath", and it does not say anything about mold resistant. Silicone 2 takes a much longer time to cure before its safe to add water though so better to stick to 1.

^^^That will work just for for baffles^^^

There are better choices if you need real structural integrity, but baffles will have little or no stress on them so it works great. GE 1 W & D is holding many in for me and had for 25+ years in a few cases.

Momentive RTV 108 or 103 would work better, but if you're just putting in baffles, GE would work too.

Uh, I was recommended the GE product for building a small aquarium (the frameless 15 ref'd in my sig) - am I going to have a problem with a tank 12" wide and 8" high, eurobraced??? I'll rebuild it if I have to but I'd really rather not.

[billdogg]

This is just my opinion, but for something that small I would think it would be good enough.

Don't use any with mildacides and be sure it's fully cured before putting it in the water.
