Review on 💧 KEDSUM 550GPH Submersible Water Pump: Ultra Quiet with High Lift, Perfect for Fish Tank, Pond, Aquarium, Statuary, Hydroponics! by Toni Miller

DO NOT USE FOR AQUARIUMS! Although this pump pumps water, it is unsealed and allows the internal lubricant to mix with the water being pumped. I tested pure RODI with a TDS meter at 0 and after submerging this pump and turning it on, the water read 48 on the TDS meter after 15 minutes. Buyers Be Careful Especially When Using It In A Reef Aquarium.
