I only use acrylic tanks (8 years) and every one I have owned has had tons of crazing or developed crazing. Never have I ever seen one break or leak but if it looks like seam is separating I would be concerned. 400 gals is alot of head pressure and weight. Talking like 1.5 tons. (3000+ lbs) ?I just acquired a 400g tank and i noticed that on the left rear bottom corner of the tank i see some crazing or seam separation (see attached picture). Kindly let me know if this is a critical threat for a blow up or not. Thank you.

I don't need to drill holes to inject the weldon right? Just inject where the edge of the acrylic panels meet?Inject a little weldon 4 in that spot only. Go over that bottom seam and the side seam with weldon 40 by tipping the tank. Should fix it
