Marc,
It can't be reinforced. The tank manufacturers I have spoken with, including James at Envision have said replacement is the only option. Trying to glue on a patch will not work because over time the crazing will grow beyond the patch. Plus the glue itself could cause even more damage. Since you have worked with acrylic quite a bit, I am sure you are aware of how the glue would react with the cracking.
The good news is that it is not seeping yet. The bad news is that Eco-Tech has dis-owned me. Sucks pretty bad since I weathered major issues throughout my ownership experience. The latest "suggestion" from Eco-Tech is that we drill out the crazed areas and install bulkheads, but they continue to claim that my tank is incorrectly manufactured, even though they have never seen it, nor have any of their tank experts.
I have an above ground pool coming just in case this thing blows.
Gabriel, you know I nearly round-filed my Tunze nano because it was a total piece of junk, but then Dahn Nguyen modded it to run extremely well. I am going to put a Vortech in his hands, and see what he can do.
I had talked with Eco-Tech at length about modding the motors and at the time, Tim told me that installing a fan on the shaft would keep the pumps much cooler and solve my over-heating issues. Unfortunately, that was one of the bait-and-switches, where they decided to send the subject pump back without the mod. telling me that if I ran the pumps on pulse, they wouldn't over-heat. That is indeed true so far, but the pump area pictured above is from one of the pmps that had yet to get a WWD swap out.
I am not a happy camper. And this tank is built into the tank room, so removing it would include tearing out the wall and sliders, and I just cannot imagine the misery that will cause. Every Vortech I have seen in person was running at an external temp. above 135F and I have recorded temps. near and above 150F.
