Tips/stories of resealing tanks?


Recommended Posts

So I'm going to be jumping into the world of resealing my tank.... Not very excited but I'm doing my research. I just got this 55 from a friend for an extremely good price but it really needs to be resealed... So I was wondering if anyone had tips or tricks that might help me! Or even good videos that would help :)

I resealed my 125, my tips are try to avoid doing it in the sun, have a partner, and use a spoon to smooth the edges instead of gloves!

Oh and also don't cut too much off of the tip of the silicone bottle. I did that, and it came out too large and gloppy, making my seams really messy. That's especially important if you use tape, because if it goes on too thick, when you remove the tape it leaves a ridge instead of a smooth nice seam.

It's not too hard to do. You'll do fine (:

I resealed a tank once and will never do it again :P I hope your experience is more pleasant lol

Have you gotten sealant yet? You can use the GE window and door silicone 1 sealant (don't get the number two kind, it has mildew resistant stuff in it). DAP is another aquarium safe kind.

Here is a good video

there are lots of good videos on youtube

Water is definitely key for getting smooth silicone edges (dip your finger in a bit of water before sliding it across the silicone along the inside edges)

EDIT sniped :P

also, you will want to get a pack of razor blades and get a nice holder for them. I found that switching out a razor I had used for awhile for a new one made getting the old silicone off a bit easier. This is the worst part of the whole thing - getting the old silicone off.

There is a neat little tool you can get from a big box reno store for making pretty nice caulking seams. They are not expensive. Some have one end to cut off the old silicone and the other end for a perfect curve. The white edge o nthe tool is silicone so it won't adhere to your new silicone and bunch up.

The big tip: Don't cut a big tip (as already posted)

Silicone won't easily stick to itself, so you'll need to cut off the old stuff.

Ugh... I waited too long to take the tape off... When I went to take it off it was already sticking together and so the tape ended up ruining the edges. I got so upset I took it all off :rofl I will attempt another day.... :wacko:

Another tips...

If u are using yr finger to smoothen the silicon,

u can actually apply little soapy water on yr finger and it will glide over giving a real smooth finishing and it wont stick to yr finger too!
