Hello, I am hoping to set up an AIO reef casa aquarium and I was hoping to keep a BTA, I recently learned that a big problem with them is on the AIO aquariums they can block the overflow grill and stop the flow, and if the ATO is in the back chamber the that part looses water. Then the ATO thinks there is no water in the tank and it floods. Is there any sort of guard for the ATO or diy solutions? Thank you!
