Review on Aquarium Exchanger Adjustable Controller Convenient by Victoria Harris

I really wanted to give this product 3.5 stars but Revain doesn't allow half stars so I rounded up to 4. Water really helps prevent accidental spills. The pump is large, so one or two pumps is enough to get the water flowing. In addition to the pump, this set also contains scrapers and nozzles for cleaning the inside of aquariums. The scrubbing nozzle was very good at removing the algae from the glass. However, the 3.5 star rating stems from two main issues. First, the pipe connection to the pump is leaking. This is not a hermetic seal. Make sure you have towels on hand to soak up the spill. Also, there are no instructions for assembling different nozzles in the kit. It's easy to understand, but the instructions won't hurt. This kit would have been a 5 star kit if it had a tight seal between the pump and hose. As it is, 3.5 stars.
