    acrylic tank repair

    what is the best method to repair cracks in acrylic? I was thinking of drilling a small hole were the crack ends then fill with weldon 3, possibly adding a small acrylic strip over the cracked area. The tank is empty so I can try any method that works best

    I would try and add some methyl chloride first in the crack with a needle dispenser... if that doesn't work, I'd laminate another piece of acrylic over that area. ( on both sides ) if its to be used a sump, looks dont really mather.

    if its for a main tank, cut that entire sheet out and put a new one in its place.

    moving.. so temporarily out of SW :b8:
    planning next tank, possibly 60x30x20 on 2x plasma.

    here are some pics of the cracks. The thing that worries me is that some of the seams are showing signs of seperation. Can I just fill these with weld on. I plan to use this tank for frags and fish.

    is that a huge crack I see on the last pic of the tank..
    if thats the case.. its pretty much dead.

    as for the seams, ya.. that 1/2" might help somewhat...

    but its in poor shape bud.. try and fix it, fill it up outside and watch it

    nono lol thats a piece of tubing. So you think I should just scrap it, the worst is at the top front seam (pic 1) the rest of the seams are pretty good

    well.. try and repair it the best you can.. doubling the seams will definitely help alot.
    once you think its ready.. fill it up.. outside.. and wait a few days.
    also, you can try and stress it a bit while its filled up.. like wiggling it .. if it seems stable and doesnt snap on you, odds are it will be ok.

    I'd personally use methylene chloride and glue pieces of acrylic right over the entire cracked areas. The 1/2" square acrylic running across the corner glued completely in and around the crack should make it stronger then ever. I can't imagine it ever leaking after that.
