Question 1

Is the hose easy to pinch?

Accepted Answer

Very easy, a few short and easy squeezes, the water is coming out.

Question 2

So as the pump is sucking all the water and grim out? Do you jus pour new water in?

Accepted Answer

I clean and service my 36 gal aquarium about once every two weeks.  With the fish remaining in the tank,  I clean the inside glass and then remove about half of the water, vacuum the gravel with the Laifoo pump and set the removed water  aside.  All accessories, plastic plants, stones and artifacts are removed and cleaned in the removed tank water.  The power filter elements  are then removed and rinsed in the removed tank water.  Filters are replaced every 2nd tank cleaning.  The tank is then refilled with RO water . Accessories and filter elements are replaced.  Clarifier, bacterial supplements and stress coat supplements are added.  Each of my power filters include a 7 watt UV lamp.  The lamps are then activated for 4 hrs to help control algae and sterilize the water.  All done for another two weeks.

The Laifoo pump works quiet well and helps to simplify the process.

Question 4

Is the suction strong enough to suck up sand? I have another brand that sucks it and I’m looking for one that only gets the dirt

Accepted Answer

If you were looking for one that will vacuum/remove the sand/gravel, this is not it. Nor are any of the normal aquarium gravel cleaners on the market. They aren't designed to remove sand or gravel. They just sift through it and remove the detritus. Most of these gravel cleaners have a filter to stop big debris from going down the hose. All in all, the suction is not enough to remove the sand or gravel. But then again it's not designed to.
