So I had a random question but when you level a rimless aquarium, do you level out the stand and then just put the mat and rimless tank on top or do you level it once everything is on? I've noticed when you try to level out the stand with the rimless tank already on, it will cause some sort of uneven points since the heaviness of the aquarium will already push the mat in some place. For example, if the tank is uneven from front to back. Hopefully I worded it clearly enough for everyone to understand. Happy Holidays!!!
