Why don't they like external overflows on rimless tanks?Rimless tanks have been around a good while…longer than 10 years. SunnyX’s famous 100 gallon rimless with t5 was around 2008/2009. I had one custom made by a very reputable builder that I wound up selling after a couple years since I was upgrading.
I’ll keep the custom tank manufacturer’s name out of it but he did share with me something to the affect of:
“Hey, I get it. They’re museum type displays. But it’s a flawed design by nature. We have to use thicker glass so that we can have a larger silicon seam at to join the panes. The taller they are the more prone they’ll be down the line to a failure. One thing people request that we’ll never do is put an external overflow box on a rimless aquarium. It’s just not smart engineering. I can build any tank I want for myself. I’d always choose a eurobrace over a rimless; not for looks but for peace of mind”.
I’m sure many people have rimless tanks that are doing just fine at the ten year or older mark. But when I hear a tank builder of premium glass aquariums personally tell me that I don’t need to hear much more to make a more informed decision now.
It’s already a flawed design of engineering. Making things worse by gluing something heavy that adds to an outward pushing force with no standard bracing exacerbates things further. I’ve had a rimless tank before. Never again. Too many issues in salt creep lines, fish jumping, not being able to provide the type of flow I like for SPS without water drip lines out of the tank…and worrying that much more about silicone seams just isn’t worth it. Sure they look nice, but I’m more about mitigating risk in reefkeeping wherever I can. Murphy’s Law has never rung more true than I’ve found it to apply to this hobby. I’ve heard of more high end rimless aquarium seam failures than plastic braced Marineland tanks.Why don't they like external overflows on rimless tanks?
Smaller the better.I'm getting a 26 gallon red sea peninsula soon and this thread has me officially spooked
Help! My acrylic tank seam is failing!! Said no one.
I can promise you that your Tenecor will not burst at the seams and flood your house. Ever. Why don't glass tanks come with lifetime leakage warranties? Just asking. Glass tanks also scratch.Look, if you could promise me an acrylic tank with the same scratch resistance as Starphire, I’m totally in!
Well to be fair there is a very long post on another forum that a gentleman lost his extremely large acrylic tank when the front seam gave way. I don't recall all the details but it was a heartbreaking read.Help! My acrylic tank seam is failing!! Said no one.
Properly bonded acrylic seams never fail. Never. Key phrase; "properly bonded". Even properly siliconed seams will fail. Eventually.Well to be fair there is a very long post on another forum that a gentleman lost his extremely large acrylic tank when the front seam gave way.

The glass tanks scratch and that is all she wrote. Acrylic can be buffed with fish still in it, Mighty Magnets sells a kit you can get scratches out with, also , if your just careful you won't scratch acrylic, it is laziness and carelessness that gets it.I can promise you that your Tenecor will not burst at the seams and flood your house.

That was ATM tank I believe, they are out of businessWell to be fair there is a very long post on another forum that a gentleman lost his extremely large acrylic tank when the front seam gave way. I don't recall all the details but it was a heartbreaking read.
