Review on 🐠 Eshopps PF300 Aquarium Overflow Box - Ideal for Up to 75-Gallon Tanks by Brian Zhao

This overflow does exactly what it is supposed to do. I had an issue with bubbles collecting in the U-tube from where the water went into the overflow box and into the U-tube, but that may be because my tank may have a higher flow rate. It also makes a lot of noise in the downspout. However, both problems can be fixed with a minor modification. I put a sponge in the overflow box to slow the water down a bit before it enters the U-tube (no more bubbles) and added an extra piece of PVC to the downspout and it's working great now. This is a great product for the money and I would highly recommend it for the smart fridge on a budget. One star off because it had to be changed.
