1. I have a couple aquariums in need of repair. Is there a fish-safe sealant that comes with a caulk gun? I tried to use the stuff in the little tube, but got most of it on my hands and got a rash.

2. Does anyone have instructions on how to make a sponge filter for a 10 or 20 gallon tank. None of the local pet stores carry them and I don't want to pay shipping on something that would normally be so cheap.

Some online places have really cheap shipping. You can also check aquabid.com. If nothing else you can see some homemade ones there and get ideas.

They do have the silicone sealant in a big caulking gun tube.

I hear GE Silicone 1 is safe for aquariums, but GE Silicone 2 isnt. They fit in caulk guns.

Use GE silicon and aquaclears filters use sponges as their filtration stage. All kinds of places online offer low shipping.

GE Silicone 1 indeed.

DIY sponge filter--there is a DIY article in the DIY section. I made one easy as pie. Basically:
1. Old plastic fish food container
2. Tubing, maybe 1" diameter or so
3. Fill the container with media/gravel
4. Filter floss around the top (optional)
5. Drill hole in tubing
6. Fit air line through it to the bottom
7. Connect to air pump
8. Enjoy

Actually, drill the hole in the larger tube and thread the air line through first. Much easier that way. I have one like I am describing ready to go.

I would use just enough gravel to keep it down and the rest sponge.

You can use any brand silicone. GE isnt the only "Fish safe" silicone. Just make sure, and this is the only thing that matters, is that its 100% silicone with no additives, IE: fungicides
