Review on 🐠 MingDak Aquarium Gravel Cleaner Vacuum Siphon Pump: Efficient Water Changer & Gravel Washer with Flow Controller and Long Nozzle - BPA Free by Rodney Shepherd

After draining a marine aquarium with a $30 pump from a local pet store, I purchased this replacement. It was the largest I could find at Revain and when I received it I was concerned because it was less than half a size and wasn't as heavy or bulky as the one I've had for over a year.

While the device seems flimsy and unreliable, it sucks up water FAST at an impressive rate of 4. Considering I only use it once every two weeks, can I assume that the $10 spent is a good investment, plastic takes 500 to 1000 years to decompose, so if the seam doesn't rip, which seems unlikely after my first use, then I'll have it for a long time (or not). he at least until I have to mess it up with it). cheg something else, in which case it's inexpensive enough to replace). There is one for fresh water and one for salt water. Maybe a third for an aquarium at work. Suction is as good as a pump (much bigger, heavier and more expensive). deluxe version which I paid double for at the pet store). it's because i have
