Review on 🔵 Lee's 40S/55 Undergravel Filter, Original Design, 12x48" or "Lee's 40S/55 Original Undergravel Filter, 15x36 by Robin Brinks

Restoring our 56 gallon (18x36) aquarium after about 6 months of not using. I'm tired of draining and cleaning the tank every 3-4 months. For example, there are fish, but you don't need to clean the aquarium that often. Some of what I've read suggested an underground filter and pump, so we hooked that up to a Marineland PH0550 power head and everything seems to be working fine. It was possible to cover almost the entire bottom of the tank, creatively positioning the part and knocking out the necessary battens. Lost a star because A. not providing enough "rubbers" to fully hold the pieces together and B. using very thin vertical edges.
