The inflows are particularly the issue for most folks, or trying to get the CO2 tubing off a diffuser.
It's the cuts made into the tip, very hard to make it both strong and offer the vents.
A simple solution is to add a clear rubber tubing to such tips and then use SS mesh or have only the tips available to sell and have the U tube separate.
This way you can add and remove them easily to clean and service.
Additionally, you could add/swap many different types of outflows and inflow designs and not just to ADA tanks, but to any return and inflow system using siphons.
It'd still look pretty, but a few clear rubber connectors would make a world of difference. Same for their tanks, add another 2-3 mm in glass thickness= add 5 more years to the tank warranty. Cost more, but the hey? They are not that concerned about their high pricing anyway. Being $$$$ on everything and then going cheap on glass thickness?
I do not know about that.
