Advice? Acrylic Tanks

Is there anyone out there that has a lot of experience with acrylic tanks? Specifically how to repair a crack and cleaning and buffing procedures? I bought a used tank that while removing it from a house, the person that was taking care of selling it dropped it on one of the corners and it cracked. It did not quite penetrate the seam but it is on the bottom and without repairing it I am not gonna set it up. It also needs a good cleaning and scratches removed. I would like some advice on this please. Thanks in advance.

 

@Turbo's Aquatics does a lot with acrylic . He may be able to steer you in the right direction . Maybe take a detailed pic too may help .

 

Where is the crack? Can you get a close up of it?

The sanding and reinforcing is the easy part. Just a little elbow grease.

 

The third pic is from the under side. Hard to get good pics of it.3/4" all the way around except top and that is 1/2". And I do realize that the fixing definitely comes before the cleaning! Lol. The damage is on the bottom corner on the end with the overflow.

Its not horrible

Here is what I would do if it was mine.

First you will need to make it incredibly clean, especially on the inside where that seam is.

Weld on make a couple products I have used. Weld on 18 & weld on 42.

Tip the tank up so that damaged end is pointing down, and fill that corner with weldon. It will harden as hard as the acrylic and make it very strong. Try to tilt it so you dont get a ton on the viewing panel. I usually do all the seams so it basically looks like caulk in a glass tank.

Then if you are happy with it, start wet sanding the viewing panes. Start out with 2000 or so, and work your way to 5000

 

I'd be tempted to glue a small block of acrylic on the inside of the corner after it was completely clean using some weldon 4 or 16

 

Is that the 300g that's been on Craigslist for a while now? Kind of hard to tell the dimensions from the pics.

 

I got it off of craigslist, yes
6' long
3' tall
30" deep? I think...

 

Where do they sell this weld on?

 

Ebay, amazon, plastic companies

 

Ok. Thanks!

 

Saw it in person yesterday and personally I wouldn't try and repair it myself. You need to get a professional to look at it in person and if possible have them repair it for you. @Turbo's Aquatics could that end panel just be cut off the good side of the crack? Then just rebuild the end?

 

If ur gonna b around the Cedar Rapids area any time soon I would love to have u stop by and take a look at it first hand.

 

Cut the corner out at a double 45°. Hone the cut to true flat. Take a small inch cube of acrylic and Weldon it in, cut the excess material away and hone it flat, fill corner as xroads suggested and done. No more fracture and corner reinforced. You can get a cube for a few bucks online.

 

If anyone has the time to help me with this it would be greatly appreciated being that I know nothing about acrylic. I'm sure I could come up with something to make the time and help worth ur while.
