Just picked up this new 300g.. a lil worried about some of the 'clamshell' bubbles in the seams. Also seeing some stress fracture/crazing..

I am thinking of doing triangular braces on the tops and bottom corners.. then doing all the seams with some 1/4"x1/4" acrylic stripping.. going to bead the seams with Weld-on #16..

Also has a slight crack in one of the opening in the top - right in the place where large acrylic tanks tend to 'fail'.. I think I will also be re-enforcing all of the openings on the top with some 2"x1/4" stripping in a square pattern around the openings..

Needs some acrylic buffing too.. that's easy stuff.

The overflow box got mangled by some idiot with a dremel tool.. Think I am going to shave the whole thing down to provide an even edge, and then apply new 'teeth' for the overflow.. or some sort of grating so fish don't climb into it.. also need to try to fit in a turn pipe, inside that tiny overflow.. don't think I can make the 'U' shape but atleast bring a pipe up inside of it with a strainer, so it doesn't make a loud splash during its 30" descent.. Genius guy also siliconed in the bulkhead inside the overflow box, which made the tank hard to move because we had to keep it on it's side because the bulkhead attachment sticks out about 4".. I hope no one set it down on the bulkhead before I got the tank.. I checked around, and it didn't seem to have any stress issues around the opening.

The bulkheads in the back were jacked up - the last guy to own the tank kept his coldwater native fish in it before he would eat them.. So I need to un-silicone these crazy PVC threaded fitting and plumb normal bulkheads obviousl

Can anyone provide some suggestions or better plan of action?


Fun project - worth the trade for a 125g.. :D heres the DIY/trade thread http://www.monsterfishkeepers.com/forums/showthread.php?t=166287&highlight=fishroom

If looks are a concern, then beading the inside of all the seams will be your best course of action. If the looks don't matter, then be on the prowl for some 3/4" square stock to glue in the corners.

For my next idea I am going to need a camera. Brb.
 
To repair the clam shell type defect and separating seam, first try that thin weldon glue to see if it will soak in by capillary action. If not, use a dremel with a metal toothed blade to open the area and then fill it with the Weldon 16.

To make the tank more appealing, you can cover the repaired seams with some wood molding. Stain or paint it to match the stand and hood.

just get a hypa dermic needle and inject some weldon right into theseam.
