This is my very first acrylic project I ever did. It is the sump for the 144g Miracles tank I designed for one of my clients after their tank started to crack out. It is still in operation, but I am planning to replace it with one that incorporates the ATO and has a better layout. This one pushed 3000GPH via a BeanAnimal drain system and surprisingly there is not a big microbubble problem, even though the operating water depth is only about 6-8" I installed an additional baffle after I determined that the long span with no euro was just too much bowing for my taste.
